CHICAGO – Chicago police arrested a 14-year-old boy for impersonating one of their own on Saturday.

The boy, who has been charged as a juvenile for impersonating an officer, walked into the Grand Crossing (3rd) District station, dressed in a Chicago police uniform, police spokeswoman Monique Bond said. The boy was with another police officer for a period of time, but did not get behind the wheel of a squad car, she said.

The boy was also savvy enough to sign out a police radio and a ticket book, according to a source. The source also said the boy went on traffic stops with the officer he went on the street with.

After his tour was over, a ranking officer became suspicious of the boy. The source said the ranking officer discovered he was not a real police officer when he couldn’t produce any credentials.

The source said the boy had an empty holster and a newspaper in place of a ballistic vest in his vest carrier.

Bond described the boy as part of a community program that allows youth to interact with Chicago police officers.

“The boy was not armed and the matter is under investigation with Internal Affairs,” she said.

Bond also said that how the boy acquired the police uniform was under investigation.
