Four Los Angeles Police officers were injured during a clash with protesters at downtown's monthly ArtWalk event that was sparked by a sidewalk chalk drawing demonstration.
Officers arrested 19 protesters, including nine for vandalism, three for assault with a deadly weapon on a police officer, two for failure to disperse, two for resisting arrest, two for blocking traffic and one for attempted assault with a deadly weapon on a police officer, reports the Los Angeles Times.
One officer suffered a minor concussion after being hit in the head by an object thrown by the crowd.
