Brian Gavidia, a 29-year-old U.S. citizen, was detained and interrogated by armed Border Patrol agents at a tow yard in Montebello during a roving patrol. Agents pushed him against a metal gate and demanded to know where he was born, asking specific questions about his birthplace despite his repeated assertions that he was American and attempts to show his Real ID. Agents took his identification and detained him for investigation of interference in an enforcement operation before releasing him after confirming his U.S. citizenship. The incident occurred during broader Border Patrol sweeps across Southern California targeting largely Latino neighborhoods and raising concerns about racial profiling.
