Police: 7 cops to blame for impersonator

Police in Chicago say an internal investigation shows seven officers broke department rules when a 14-year-old boy allegedly impersonated an officer for several hours.

Superintendent Jody Weis is calling on the U.S. Secret Service for an independent security review after the Jan. 24 security breach.

Weis discussed findings of the investigation Tuesday.

Authorities say the boy wore a uniform and entered a South Side police station through an unlocked back door. He pretended to be an officer for hours, including time in a patrol car with another officer. He was discovered after officers noticed his uniform lacked a regulation star.

The boy's name hasn't been released. He's pleaded not guilty in juvenile court.

The teen is no longer in custody but must wear an electronic monitoring device.
