Criminals posing as US immigration officers have carried out robberies, kidnappings, and sexual assaults in several states, warns a law enforcement bulletin issued last month by the Federal Bureau of Investigation. The bureau urges agencies to ensure officers clearly identify themselves and to cooperate when civilians ask to verify an officer’s identity—including by allowing calls to a local police precinct. “Ensure law enforcement personnel adequality [sic] identify themselves during operations and cooperate with individuals who request further verification,” it says.

First reported by WIRED, the bulletin cites five 2025 incidents involving fake immigration officers and says criminals are using Immigration and Custom Enforcement’s heightened profile to target vulnerable communities, making it harder for Americans to distinguish between lawful officers and imposters while eroding trust in law enforcement. A review of public reporting confirms four of the five cases described in the bulletin. One appears to have gone unreported, suggesting the FBI drew in part on internal law enforcement information. The document was first obtained by the transparency nonprofit Property of the People.

On August 7, according to the FBI, three men in black vests entered a New York restaurant claiming to be ICE agents. Inside, they tied a worker’s hands and pulled a garbage bag over the person’s head. Another, believing the burglars’ story, surrendered themselves, only to be kicked to the ground and tied up as the intruders robbed an ATM.

The bureau’s advisory urges agencies at every level of government to coordinate to “verify legitimate versus non-legitimate operations” attributed to ICE—a call that frames the wave of impersonations as a national law-enforcement concern.
