A Charleston County Detention Center guard is out of jail in more ways than one, after investigators say he illegally posed as a sworn law enforcement officer.

Ken C. Duncan, 26, has been released from jail on a $10,000 bond after being arrested Nov. 26. Duncan is charged with impersonating an officer and unlawful use of a blue light.

Affidavits provided by the Charleston County Sheriff's Office show Duncan was spotted on Interstate 26 Nov. 22 wearing his detention center uniform and engaging a blue-and-amber LED light bar installed in the rear windshield of his personal vehicle.

CCSO affidavits show the person who reported Duncan said he was in front of her on the interstate at the time he activated the light, but also said the same vehicle (a silver Ford Fusion) had followed her home a week earlier.

The witness reported Duncan to the Goose Creek Police Department, which then turned over the investigation to the Charleston County Sheriff's Office.
