A San Mateo County Sheriff's deputy caught three teens around 3:30 a.m. Saturday morning, after pulling over their car for not using a turn signal, in Half Moon Bay.
After pulling over the car, the deputy noticed that the car had strobe lights installed behind its grill, and side mirrors, resembling a police cruiser.
It also had an amber-colored flashing light bar in the rear and a public address system.
A sixteen-year-old in the car was reportedly wearing a bullet proof vest and in possession of a military police badge, which he claimed his uncle had given him to wear for Halloween.
After investigating the items, they were reported stolen from a man in Vallejo, on Friday.
The teen was booked into juvenile hall on stolen property charges. The driver was cited on suspicion of having a replica police car, and released to his mother. The third was cited a misdemeanor warrant, and also released to a guardian.
All of the boys are juveniles, therefore their names have not been released.
