Masked federal officers detain man in Glen Park car stop

Masked federal officers forced a man out of a parked car on Mangels Avenue in Glen Park just before 8:15 a.m. Wednesday, pinned him to the pavement, searched his pockets and loaded him into an unmarked vehicle in a detention that neighbors said lasted about five minutes.

Video and eyewitness accounts showed officers in tactical gear surrounding the vehicle, with at least one wearing a vest labeled “police federal officer.” The car left behind at the scene was reported to be registered to Marvin Godoy Calderon, and a federal habeas petition filed the same day in U.S. District Court identified Marvin Dick Godoy Calderon as the petitioner. San Francisco Superior Court records reportedly showed no active criminal cases under that name.

District 7 Supervisor Myrna Melgar said ICE officers had taken a man into custody and that he had legal representation, but she could not say whether the detainee was Calderon. The San Francisco Rapid Response Network was alerted to suspicious activity in the area, though it had not verified an arrest at the time of its report. Later, an activist reported seeing the same man brought into the ICE field office at 630 Sansome Street.

The encounter hit Glen Park as a broader fight over masked federal policing was already unfolding in San Francisco. Neighbors and advocates described the stop as abrupt and unnerving, saying they rushed back inside to warn family members and neighbors as officers moved in and out of the block in a matter of minutes. Department of Homeland Security, ICE and Customs and Border Protection did not immediately respond to questions about the operation.

The detention also sharpened a local policy debate over accountability. San Francisco’s sanctuary ordinance generally bars city employees from using city resources to assist ICE in civil immigration enforcement unless required by federal or state law. In March, supervisors Bilal Mahmood and Chyanne Chen were preparing legislation that would require the San Francisco Police Department to verify the credentials of plainclothes or masked federal agents and document that verification on body-worn cameras.

California lawmakers have moved in the same direction. The No Secret Police Act, SB 627, was enacted in 2025 and is aimed at restricting masked law enforcement officers, requiring officers to be identifiable through their uniforms. For residents trying to assess whether a detention is lawful, the public record should show the agency involved, whether officers identify themselves, and whether local police have verified credentials and recorded that check. In this case, the central questions remain the same ones that Glen Park neighbors were asking as the unmarked vehicle pulled away: who was acting, under what authority, and who is accountable.
