Los Angeles — Federal immigration authorities arrested 44 people Friday across Los Angeles, prompting clashes outside at least one location as law enforcement threw flash bangs to try to disperse a crowd that had gathered to protest the detentions.

Federal immigration authorities carried out enforcement activities at several locations in Los Angeles on Friday, with some clashes breaking out as crowds gathered outside a warehouse and other locations across the city to protest the activity.

Two separate possible immigration enforcement operations involving Homeland Security Investigations (HSI) and FBI agents were underway Friday morning in both the Westlake District and downtown Los Angeles.
