12 people were arrested Tuesday night at a city council meeting in Stockton. Police said the arrests happened during a protest organized by Black Lives Matter.

According to police, three men were arrested for assaulting an uninvolved homeless man during the protest. While police attempted to help the homeless man, protestors charged the scene, according to police, and had to be pushed back.
