Police are investigating an incident involving a vehicle that looked like a DPS patrol car in Glendale.
DPS alerted Glendale Police around 2 p.m. Monday after hearing of a suspicious vehicle on Grand Avenue in Glendale.
The vehicle was described as a "possible prior service DPS vehicle" with a woman driving, flashing her headlights at other drivers. The person who reported the driver says there were blue markings on the rear bumper.
Police initially said she may have been attempting to pull other drivers to the side of the road, but the exact circumstances are under investigation.
The driver has not been located but police say there is nothing to indicate that she was impersonating an officer at this time.
