Opinion by
Appeal is taken to this Court from judgment of sentence rendered by Judge Warren K. Hess following jury verdict of guilty of possession with intent to deliver a controlled substance1 and conspiracy.2 Previous to the September 27, 1973, trial, a suppression hearing had been held on September 6, 1973, before Judge Frederick Edenharter, wherein appellant sought to suppress evidence obtained by means of search warrants for the body of appellant and for the automobile which he was using at the time of arrest. Post-trial motions were filed, argued, and denied.
Based upon affidavits3 of one Jere Verdone, a Reading, Pennsylvania, police officer, District Justice Ralph B. Brbneiser issued search warrants for the body of appellant and for a “Cadillac Sedan” in which appellant, one Theodore Covel and “two other unknown persons” were known to be riding. On April 30, 1973, at approximately 9:00 P.M., in the City of Reading, Pennsylvania, said vehicle was stopped, and the warrants were executed upon the car and appellant. Occupants were appellant and his two co-defendants below, Covel and Anthony Spade. Evidence was seized which later proved to be *526heroin, packaged in 169 glassine bags, each bag containing approximately 100 milligrams of the substance. Appellant and the others were held for preliminary hearing and charged with the aforestated crimes.
Appellant challenges the existence of probable cause for the Magistrate’s issuance of both a body and an automobile search warrant and alleges that said lack of probable cause in the affidavit should have served below as grounds to suppress evidence of crime, to-wit, 169 glassine bags of heroin found in the Cadillac automobile in which appellant and two co-defendants were riding. The six paragraph affidavit provided to the Magistrate becomes the focus of our study.
When a law enforcement officer applies for a search and seizure warrant he makes an affidavit before an issuing authority. When the information in support of the issuance of the warrant has been received in substantial part from an informer, the issuing authority must be able to determine from the contents of this affidavit that the officer knows “the underlying circumstances from which the informer concluded that the suspect possessed the fruits or evidence of a crime” and that the officer has “some reasonable basis for concluding that the source of the ‘tip’ was reliable”. Aguilar v. Texas, 378 U.S. 108, 84 S.Ct. 1509, 12 L.Ed. 2d 723 (1964), Commonwealth v. Milliken, 450 Pa. 310, 300 A.2d 78 (1973), or as we said in Commonwealth v. Cosby, 234 Pa. Superior Ct. 1, 6-7 (1975), the statement of facts given by the officer must be “sufficient to enable the issuing authority to make two independent judgments:
(1) That the affiant is probably correct in his belief that the informer is reliable; and
(2) That the information received from the informer is probably reliable.”
Such facts being set forth in the affidavit the issuing authority may conclude that probable cause exists for the issuance of the search and seizure warrant.
*527The affidavit4 establishes that the affiant, Police Officer Lt. Verdone received information from three different informants and in addition had some personal knowledge pertinent to proof of probable cause. To facilitate clarity of expression, the informants will be referred to as informant No. 1, the one referred to in paragraph (1) of the affidavit; informant No. 2, the one referred to in paragraph (3) and informant No. 3, Officer Schwartz referred to in paragraph No. 4.
Informant No. 1 told Lt. Verdone that two men were involved in narcotic drug traffic in the City of Reading. He gave Officer Verdone the following details: that their names were Theodore Covel and “Tiny” Barrett, that these two men were in a partnership to sell heroin, that they are selling it in the City of Reading, that the two of them are buying heroin in Philadelphia, that they pick it up by driving a car there; that appellant was using a black Cadillac sedan of approximately 1969 vintage and that appellant’s real name is James Barrett. This information was given to Lt. Verdone on April 27, 1973 and the application for the search warrant was made on April 30, 1973.
Both Covel and the appellant were known personally to all members of the Reading Vice Control Division as persons who had been involved in narcotic drug traffic.
Informant No. 2 told Officer Hymon of the Reading Police Department at about 6:00 P.M., on April 30, 1973, that Theodore Covel and Tiny Barrett have made a trip out of town to get heroin and bring it back to Reading for resale; that the two men left that same afternoon but he did not know the exact time. Officer Hymon related this information to Lt. Verdone.
Informant No. 3 was Officer Schwartz of the Pennsylvania Turnpike Police. He informed Lt. Verdone that he personally observed a black Cadillac sedan which had a *528temporary Pennsylvania registration plate and had four occupants in the car, entering the turnpike at 4:45 P.M. on April 30, 1973, through the Morgantown toll gate headed for Philadelphia. Officer Schwartz described two of the occupants precisely, which descriptions were those of Theodore Covel and Tiny Barrett.
The affidavit establishes that Lt. Ver done had a reasonable basis for concluding that informant No. 1 was reliable for the reason that the same informer had on two other occasions within the past week provided Lt. Ver done and another agent of the Pennsylvania Bureau of Drug Control information relative to traffic of narcotic drugs in the City of Reading and related activities of suspected drug sellers, which information was checked out and found to be accurate.
As to informant No. 2, while there is no recital as to his past performance, it is reasonable to infer that inasmuch as he was corroborating two other reliable informants, he also was reliable.
As to informant No. 3, the Pennsylvania Turnpike Officer Schwartz, his employment and position form a reasonable basis for concluding that the information he supplied was reliable. The one test required by Aguilar and Millilcen relating to the reliability of the informers is met.
The informers, individually and collectively, gave underlying circumstances to Lt. Verdone, the affiant. Informer No. 1 gave the full names of the suspects, together with the nickname of appellant. He stated that the two suspects were in partnership to sell heroin, that they were in fact selling it in the City of Reading, that they bought the heroin in Philadelphia where they would pick it up by driving a car to Philadelphia and that the appellant was using a black Cadillac of the approximate year 1969. Informant No. 2 provided information that the two suspects, giving their names, had made a trip out of town to get heroin and to bring it back to Reading for re-sale, *529that this trip was sometime in the afternoon of April 30, 1973, but the exact time was not known. Informant No. 3 provided information that a black Cadillac sedan bearing a temporary Pennsylvania registration plate, having four occupants in it, of which two of the occupants fit the precise description of Covel and Barrett had entered the Pennsylvania Turnpike at the Morgantown toll gate at 4:45 P.M. on April 30, 1973, headed for Philadelphia.
From all these underlying circumstances, Lt. Verdone could justifiably believe that informer No. 1 had properly concluded that appellant and the Cadillac automobile would upon its return to Reading possess evidence of a crime.
Appellant complains that part of the information supplied by the informers was hearsay. Hearsay evidence may be properly considered by a Magistrate in determining probable cause when it is substantiated: United States v. Harris, 403 U. S. 573, 91 S. Ct. 2075, 29 L. Ed. 2d 723 (1971) ; Commonwealth v. Ambers, 225 Pa. Superior Ct. 381, 310 A.2d 347 (1973). We said in Ambers that there are four bases to be considered in crediting hearsay; Commonwealth v. Falk, 221 Pa. Superior Ct. 43, 46-47, 290 A.2d 125, 126-127 (1972). These factors are as follows:
“(1) Did the informant give prior reliable information ?
(2) Was the informant’s story corroborated by any other source?
(3) Were the informant’s statements a declaration against interest?
(4) Does the defendant’s reputation support the informant’s tip?”
In the present case the principal informant, informant No. 1 had given prior reliable information. Each of the informant’s stories was corroborated by other sources and the (defendant-appellant’s) reputation supported the informant’s tips. In regard to appellant’s reputation the *530affidavit established that both appellant and Covel were personally known to the Reading Vice Control Division as persons who have been and are involved in the narcotic drug traffic in the City of Reading.
Lt. Verdone knew that in April of 1971 appellant was reputed to be a partner with one Stewart in the operation of heroin traffic and he also knew that Theodore Covel had a prior conviction for heroin in New York City and had been a constant user of heroin while a resident of Reading except for the times when he was using a substitute drug. A police officer’s knowledge of a suspect’s reputation is an element which an issuing authority may consider in determining the credibility of hearsay. Chief Justice BURGER in United States v. Harris, 403 U.S. 573, stated at page 583 as follows:
“We cannot conclude that a policeman’s knowledge of a suspect’s reputation — something that policemen frequently know and a factor that impressed such a ‘legal technician’ as Mr. Justice Frankfurter — is not a ‘practical consideration of everyday life’ upon which an officer (or a magistrate) may properly rely in assessing the reliability of an informant’s tip. To the extent that Spinelli prohibits the use of such probative information, it has no support in our prior cases, logic, or experience and we decline to apply it to preclude a magistrate from relying on a law enforcement officer’s knowledge of a suspect’s reputation.”
Whatever elements of hearsay were involved in the informants’ statements, they were adequately substantiated by consideration of the factors forming the bases for crediting such hearsay. Not all of the factors were satisfied. However, three of them were satisfied as to the principal informant (informant No. 1) and others were met in relation to the additional informants. All four factors need not be satisfied for the court to uphold the validity of the warrant. Commonwealth v. Falk, supra.
*531We find that the affidavit adequately supports the Magistrate’s issuance of the search warrant and affirm the judgment of sentence.
Cercone, J., concurs in the result.

Affidavit in Support of Search Warrant.
FOR ADDITIONAL REASONS OF PROBABLE CAUSE, SEE THE ATTACHED AFFIDAVIT RIDER.
1. In that, upon information received from a reliable and confidential police informant, who on two prior occasions within the past week, provided to Lt. Ver done and Agent Palmer of the Penna. Bureau of Drug Control Information relative to the traffic of narcotic drugs in the City of Reading and related activities of suspected drug sellers, (unlawful drug sellers,), information which was checked out and found to be accurate: the information received this date from the confidential and reliable police informant was that Theodore Covel and “Tiny” Barrett, both persons whom are known personally to all members of the Reading Vice Control Division as persons who have been and are involved in the narcotic drug traffic in the City of Reading, are in a partnership to sell heroin, and are selling heroin in the City of Reading. The informant further stated that the two are buying the heroin in Philadelphia where they pick it up by driving there by car. “Tiny” Barrett’s real name is James Barrett. This informant gave this information on 27 April 73.
2. In that, upon the personal knowledge of Lt.

Barrett was not arrested nor convicted of any drug violation as of this date, however.
*5323. In that, upon information received from Officer Hymon of the Reading Police Department at about 6:00 P.M. this date, 30 April 73, that he had received information from an informant of his that Theodore Covel and Tiny Barrett have made a trip out of town to get heroin and bring it back to Reading for re-sale.
