Increase In ICE Arrests Triggers Alarm In Bay Area

BAY AREA, CA — New ICE arrests outside Marin County Jail and at routine appointments have fueled alarm among immigrant advocates, as legal observers expand rapid-response efforts amid what organizers describe as a sharp rise in detentions.

Immigrant advocates in Marin County say a recent cluster of U.S. Immigration and Customs Enforcement detentions — including arrests outside the county jail and during routine immigration appointments — signals a troubling shift that has rattled undocumented families and intensified local response efforts.

The Marin Rapid Response Network reported four undocumented Marin residents were detained by ICE after release from the county jail in March and April, a pattern the executive director, Lisa Bennett, said is rare.

Bennett said that the network has documented 29 Marin residents detained since January 2025, with most arrests tied to federal immigration check-ins or court proceedings in San Francisco.

She said a woman was detained while appearing for fingerprinting at a U.S. Citizenship and Immigration Services office in Santa Rosa — an encounter she described as highly unusual.

Bennett also recounted the detention and swift deportation of a Marin mother and her children after an ICE check-in.

Marin County Sheriff Jamie Scardina told the Marin Independent Journal his office could not independently verify two arrests said to have occurred outside the jail in San Rafael, though he confirmed ICE agents were present in the jail lobby during inmate releases on April 13. California law limits law enforcement cooperation with federal immigration authorities, though Scardina said his office responded to 23 of 141 ICE requests for release information last year.

The detentions have pushed the Marin Rapid Response Network far beyond its original role as a hotline. The volunteer network, founded in 2018, now fields daily ICE-sighting calls, coordinates legal observers, connects detainees to attorneys, and helps support families facing economic hardship after arrests.

The organization organized a bilingual online training for employers confronted by an ICE raid — another rare event in Marin, but one that has become more plausible. "The only thing stopping ICE is employers knowing their rights," Bennett said. For example, to access the kind of records that ICE wants, agents need a warrant signed by a judge. "I don’t think our businesses are ready," Bennett said.

The Marin Independent Journal also reported that a parallel grassroots effort has distributed thousands of whistles at farmers' markets and community events, with volunteers training residents to use them as neighborhood alerts when ICE agents appear — a tactic supporters say prioritizes warning vulnerable families before agents can act.
