Video showed authorities taking protesters into custody. Thirty-six people were arrested, some on suspicion of rioting and one on suspicion of battery on an officer, police said.
"The LAPD’s objective is to ensure public safety for ALL, while facilitating the First Amendment rights of those peacefully demonstrating," the LAPD said. "However, this was not a peaceful demonstration.
"Protestors threw a police officer to the ground, used construction debris, road signs, tree branches, and blocks of concrete to obstruct Century BLVD while attacking uninvolved passerbys (sic) in their vehicles. This unlawful behavior is dangerous and will not be tolerated. Approx. 36 protesters were arrested and booked for 404.6 PC (Rioting) and at least one arrested for battery on a police officer."
