A Kansas police officer has been charged with firing at an occupied car on Christmas morning.

The Kansas City Star reports that Wyandotte County prosecutors charged 32-year-old Michael Mills on Tuesday with aggravated assault and criminal discharge of a firearm at an occupied vehicle. He has been placed on unpaid administrative leave.

Mills, a Kansas City, Kan., police officer, was off-duty at the time of the alleged shooting, which happened between 1 a.m. and 2 a.m. Sunday near his home. One shot hit the car’s right rear quarter panel, but no one was hurt.

Mills was later arrested and released on $25,000 bond. He could not immediately be located Tuesday for comment, and it wasn’t clear if he has an attorney.

Authorities didn’t disclose what led to the shooting.
