OPINION
Vamsidhar Vurimindi appeals the District Court’s order denying his motion for an injunction. For the reasons below, we will affirm the District Court’s order.
In January 2013, Vurimindi filed a civil rights complaint against Appellees alleging claims of bad faith, harassment, and official lawlessness. He sought to enjoin his criminal prosecution for harassment and stalking. The District Court denied his motion for a TRO, preliminary injunction, and permanent injunction, and dismissed his complaint without prejudice to his filing an amended complaint. Because the *91state court handling his criminal charges had found Vurimindi not competent to stand trial, the District Court placed the matter in suspense until Vurimindi was found competent. Vurimindi filed a notice of appeal.
We have jurisdiction over the District Court’s denial of the injunction pursuant to 28 U.S.C. § 1292(a)(1). We review the denial of a motion for a preliminary injunction for an abuse of discretion but review the District Court’s underlying legal conclusions de novo. Brown v. City of Pittsburgh, 586 F.3d 263, 268 (3d Cir.2009).
The District Court concluded that it should abstain from interfering with Vuri-mindi’s criminal litigation in state court under the doctrine of Younger v. Harris, 401 U.S. 37, 91 S.Ct. 746, 27 L.Ed.2d 669 (1971). The District Court did not err in doing so. The requirements which must be met before a federal court may abstain are that there must be pending state proceedings which (1) are judicial in nature; (2) implicate important interests; and (3) afford an adequate opportunity to raise any constitutional issues. Matusow v. Trans-County Title Agency, LLC, 545 F.3d 241, 248 (3d Cir.2008). Vurimindi’s criminal proceedings are judicial in nature and implicate the important interests of protecting the victims from Vurimindi’s alleged conduct. Vurimindi has not shown that he will not have an adequate opportunity to raise any constitutional issues during his proceedings. Because we agree that abstention was appropriate, we need not reach the District Court’s alternative reasons for denying Vurimindi’s motion for a preliminary injunction.
For the above reasons, we will affirm the District Court’s order. Vurimindi’s motions are denied.
