Chicago ? A 14-year-old aspiring police officer donned a uniform, walked into a Chicago police station and managed to get an assignment — patroling in a squad car for five hours before he was detected, police said Sunday.

The boy did not have a gun, never issued any tickets and didn’t drive the squad car, Deputy Superintendent Daniel Dugan said.

Assistant Superintendent James Jackson said the ruse was discovered only after the boy’s patrol with an actual officer ended Saturday. Officers noticed his uniform lacked a star that is part of the regulation uniform.

Police said they were investigating how the deception went undetected for so long.
