Opinion by
Theodore Shubert (claimant) appeals an order of the Workmens Compensation Appeal Board (Board), which affirmed a referees decision denying his claim for com*139pensation for a job-related mental disability, pursuant to Section 301(c) of The Pennsylvania Workmens Compensation Act1 (Act), 77 P.S. §411.
The claimant had been employed by C. M. American Industries (employer) for twenty-three years when he was arrested and charged with the theft of the employers property, namely, certain steel items described as binders or ratchets. Claimant at all times insisted that the materials he admittedly placed in the trunk of his car on the night in question were scrap items intended merely to weight down his car to improve traction on an icy evening. He contended he had followed this practice with the employers approval for some twenty years during inclement weather.
Claimant, who had a history of psychiatric problems, became despondent over the accusation and criminal charges,2 as well as the termination of his long-standing employment and concomitant loss of employee benefits. Upon consultation with a psychiatrist shortly after his arrest, claimant was diagnosed as markedly suicidal, and was hospitalized immediately; he remained under a psychiatrists care for some time thereafter.
Claimant filed a petition for workmens compensation, in which he alleged that his mental illness resulted from both the employer’s conduct in directing that he be arrested at work and the humiliation he suffered upon the filing of criminal charges. Claimant’s petition was denied by the referee who found that claimant foiled to demonstrate misconduct on the part of the employer, a work-related injury, or disability due to a work injury. Upon the Board’s affirmance of the referee’s decision, claimant’s appeal to this Court followed.
*140Work-related mental or emotional disability is an injury as defined by Section 301(c) of the Act, Allegheny Ludlum Steel Corp. v. Workmen's Compensation Appeal Board (Fisher), 91 Pa. Commonwealth Ct. 480, 498 A.2d 3 (1985), and may be compensable if such illness arises in the course of employment and is related thereto. Evans v. Workmen's Compensation Appeal Board (Anchor Hocking Corp.), 87 Pa. Commonwealth Ct. 436, 487 A.2d 477 (1985). Where the causal connection between the injury and the employment is not obvious, unequivocal medical testimony is required to establish causation. Andracki v. Workmens Compensation Appeal Board (Allied Eastern States Maintenance), 96 Pa. Commonwealth Ct. 613, 508 A.2d 624 (1986).
In an attempt to demonstrate the requisite causation, claimant proffered the deposition testimony of his treating psychiatrist, who therein opined that claimants arrest at work and the subsequent criminal proceedings were related to his mental illness.
We do not doubt that claimants arrest and the lengthy resolution of the criminal charges were indeed stressful. However, the suggestion that the consequence of an employees criminal activity might constitute a psychic injury so as to warrant compensation under the Act stretches credulity. In this regard, the referee here pertinently found as follows:
8. The claimant tells that he merely took the items for the weight in helping drive his automobile upon a slippery surface. He states that the items were old, not new, and . that he had permission to take them. Claimants two witnesses support his statement that the items were junk or used rather than new.
9. Eugene D. Leagle, manufacturing manager for the employer, testified for the employer.
10. He testified that the items found in . claimants auto were new and ready for sale, that *141the employer had been missing such items from its inventory stock, and that the claimant had not received permission to use them that night.
Upon indicating his careful review of the entire record, including the testimony of lay witnesses for both parties and the testimony of the claimants medical witness, the referee found the employer’s witness more credible and concluded that claimant had failed to meet his burden of proving the occurrence of a work-related injury. In workmen’s compensation matters, the referee is the finder of fact and, within such province, determines the credibility and weight of the evidence. Mathies Coal Company v. Workmen's Compensation Appeal Board (Bellicini), 102 Pa. Commonwealth Ct. 332, 518 A.2d 335 (1986). The referee here chose to credit the employer’s witness who testified that the items removed from the trunk of claimant’s car were “completed produces] ready for sale.” This Court cannot be persuaded by the testimony of the claimant and his co-worker that such items were merely scrap metal. We are bound to defer to the referee’s conclusion even if, on the same record, we might reach a different result. Id.
Limited as we are by our scope of review,3 we find that the testimony of the employer’s representative constitutes substantial evidence in support of the referee’s determination that claimant foiled to demonstrate misconduct on the part of the employer, a work-related injury, or disability due to a work injury.
*142Accordingly, the order of the Workmens Compensation Appeal Board is affirmed.
