An immigration enforcement sweep targeting vendors on New York City’s famed Canal Street turned chaotic on Tuesday, as droves of bystanders and protesters surrounded federal agents and attempted to block them from carrying out the operation. A spokesperson for the Department of Homeland Security said the agents were carrying out an enforcement operation against sellers of “counterfeit goods" when “rioters who were shouting obscenities, became violent and obstructed law enforcement duties including blocking vehicles and assaulting law enforcement.” At around 4 p.m., an Associated Press reporter observed dozens of federal agents as they made one of a number of arrests in the area, detaining a street vendor who appeared to be selling bedazzled smartphone cases.
