An off-duty Fairfax County detective was arrested yesterday for DUI while operating his unmarked police vehicle.

On September 9th at 12:24 a.m. Deputy J.D. Hurt observed a Ford Fusion disregard a red traffic signal, nearly causing an accident, at the intersection of Courthouse Road and Hospital Center Boulevard. A traffic stop was conducted and the driver was identified as Stephen Copp, 57. Deputy Hurt determined Copp was an off-duty detective with the Fairfax County Police Department and was operating his unmarked law enforcement vehicle.

Copp had bloodshot, glassy eyes and an odor of alcoholic beverage on his breath. He was charged with DUI and the traffic signal violation and the magistrate released him on an unsecured bond. The vehicle was released to the Fairfax County Police Department and they have placed Copp on administrative leave pending an internal affairs investigation.

This was one of five DUI arrests yesterday in Stafford County! Drive sober or get pulled over.
