(AP) -- PITTSBURGH (AP) - Authorities say several people have been injured in a shooting at a psychiatric clinic at the University of Pittsburgh, and police are looking for a gunman.
Authorities did not say how many people were hit in the Thursday afternoon shooting at the Western Psychiatric Institute and Clinic.
Pittsburgh-area media are reporting that at least five people were shot. It isn't clear how many gunmen might be involved. Some reports say a gunman and a police officer were among those shot.
A SWAT team is on the scene, and buildings are on lockdown. The school is on spring break.
The clinic describes itself on its website as a top academic-based psychiatric care center. Pitt's psychiatry department is part of the clinic.
