OAKLAND, Calif. -- Police arrested a man for impersonating an officer on Wednesday after they say he tried to pull over an undercover Oakland officer.

Police say 21-year-old Antonio Fernandez Martinez of Oakland followed an undercover officer in a vehicle similar to a police cruiser. They say the car had flashing lights on its dashboard and appeared to have red and blue lights on its grill that were actually paint-covered speakers.

Police say Martinez motioned to the undercover officer to pull him over. The real cop then alerted his colleagues.

Martinez was arrested a couple of blocks away. His car was registered to someone else.

Police say Martinez is a convicted car thief and could have his felony probation revoked, resulting in a prison sentence.
