The gunfire Wednesday night hit a window, causing the glass to break and slightly injuring one of the two officers inside.
The officer was treated by medics.
The car was traveling along University Avenue, a major east-west thoroughfare. Investigators were talking with witnesses and trying to determine if the officers were the intended target.
