Police in southern California arrested a man suspected of posing as a federal immigration officer this week, the latest in a series of such arrests, as masked, plainclothes immigration agents are deployed nationwide to meet the Trump administration’s mass deportation targets.

The man, Fernando Diaz, was arrested by Huntington Park police after officers said they found a loaded gun and official-looking documents with Department of Homeland Security headings in his SUV, according to NBC Los Angeles. Officers were impounding his vehicle for parking in a handicapped zone when Diaz asked to retrieve items inside, the police said. Among the items seen by officers in the car were “multiple copies of passports not registered under the individual’s name”, NBC reports.

Diaz was arrested for possession of the allegedly unregistered firearm and released on bail.
