Someone’s gun accidentally went off in a women’s bathroom stall at a Denver college.

No one was hurt but it freaked a bunch of students out.

Cops are pretty sure it was an accident… they think a gal was carrying it in her bag when it went off. The bullet is lodged in the drywall of the bathroom stall.

Guns on campus are not allowed and the police are looking for the young woman who was spotted leaving the bathroom right after the gun went off.
