CHICAGO (CBS) — He’s an adult now, but Chicago’s infamous “kid cop” allegedly has been at it again. After fooling Chicago police into letting him on patrol in 2009 by impersonating an officer when he was 14 years old, Vincent Richardson has been arrested a third time for posing as a cop.

Richardson, now 21, was arrested in Englewood on Friday, along with another man. Police said Richardson and 21-year-old Dantrell Moore were wearing bulletproof vests, and police duty belts. They also had a police scanner and a stun gun.

In 2009, Richardson made national headlines when he dressed up as a police officer, and – despite being only 14 at the time – managed to work a full duty shift alongside real officers, and even was allowed to drive a squad car on patrol.
