A California man was arrested during a traffic stop after allegedly impersonating a police officer, according to officials.

The driver was pulled over near South De Anza Boulevard and Rodrigues Avenue in Cupertino, California, after a Santa Clara County Sheriff's deputy noticed an SUV with an expired registration, the sheriff's office said in a Facebook post on Sunday.

The vehicle was equipped with siren lights, according to the sheriff's office.

The driver was found wearing a security uniform with "police" written across it. The uniform featured a duty belt and a bullet-proof vest. He was also wearing a hat that read, "Officer Garcia."

"The suspect did not have a guard card on him either," the sheriff's office said.
