“It’s a fine line when you facilitate First Amendment . . . but these particular groups went beyond that. When you encroach upon other people’s rights and the safety of others, we have to draw the line there,” Lt. Andy Neiman said.

An LAPD officer was injured during the overnight protests when he was hit in the head with a partially frozen water bottle. That person was arrested for felony battery on a police officer and was being held on $25,000 bail.

Protesters also shut down part of the 101 Freeway in both directions at Grand Avenue for about an hour Tuesday night.
