42 Pa.C.S. § 8387: Protection of witnesses.

At the time of an application for the issuance of a restraining order or an injunction if proof of the existence of the drug-related nuisance depends, in whole or part, upon the affidavits of witnesses who are not law enforcement officers, upon a showing of prior threats of violence or acts of violence by any defendant or other person alleged to be involved in the drug-related nuisance, the court may issue orders to protect those witnesses, providing for nondisclosure of the name, address or any other identifying information pertaining to the witnesses, and such other and further relief as the court may deem appropriate.
