The unidentified demonstrator allegedly threw rocks at law enforcement and damaged government vehicles, the FBI said.

As tense anti-ICE protests in Los Angeles enter their fourth day, federal officers have ramped up law enforcement’s response – and have added one protester to the FBI’s ‘Most Wanted list.’

The unidentified demonstrator has been accused of assaulting a federal officer and damaging government property during Saturday’s protest in Paramount, a city 30 miles south of Los Angeles.

The suspect allegedly threw rocks at law enforcement on Alondra Boulevard around 3:30 p.m. Saturday, “injuring a federal officer and damaging government vehicles,” according to the FBI’s Los Angeles field office. It was not immediately clear whether the officer was injured or the extent of the damage.
