DENVER (CBS4) – A Denver Public Safety Cadet, placed on leave earlier this month for making an unauthorized traffic stop, has been reinstated to his job following a three week investigation.

On June 8, a CBS4 Investigation reported the 20 year old cadet was driving a marked Denver police cruiser on I-25 when he pulled over a driver for expired plates. The driver was an investigator for the Denver District Attorney’s Office and later reported the improper stop.

But the investigation has now revealed there was a female Denver police officer in the police cruiser and the cadet was being supervised by the officer.

“He was acting under the direction of the officer in the car,” said a spokesman for the Manager of Safety’s Office who said the cadet did violate a rule, but is not being disciplined beyond the three week suspension.
