PITTSBURGH — Pittsburgh police say an off-duty officer’s vehicle was hit by a bullet as she was driving home, but still in uniform, after her shift.

Police aren’t identifying the officer, but say she wasn’t injured in the shooting about 2:35 a.m. Thursday on Browns Hill Road.

The officer passed a red or maroon vehicle, possibly a Ford Mustang, which she saw pull into a Speedway gas station parking lot before passing a newer silver-four door sedan with tinted windows. The officer heard a gunshot and stopped to examine her vehicle and found a bullet hole in the rear passenger door.

Police don’t know whether the shot came from one of the two vehicles the officer passed or from some other place.

Police didn’t immediately find any shell casings.
