The order bars the detention of people unless the officer or agent “has reasonable suspicion” that the person to be stopped is violating U.S. immigration law.

A federal judge on Friday ruled that immigration officers in Southern California can’t rely solely on someone’s race or speaking Spanish to stop and detain them.

District Judge Ewusi-Mensah Frimpong issued a temporary restraining order after a lawsuit was filed by three men who were arrested as they waited to be picked up at a Pasadena bus stop for jobs on June 18, and after two others were stopped and questioned despite saying they are U.S. citizens.

Frimpong’s order bars the detention of people unless the officer or agent “has reasonable suspicion that the person to be stopped is within the United States in violation of U.S. immigration law.”
