Los Angeles police set up a skirmish line Sunday morning as a crowd of young people donating on the street threw firecrackers and other objects at officers trying to clear the area.

CBS News reports that a mob in the Boyle Heights area was setting off firecrackers and throwing stones and bottles at LAPD officials.

Footage from the Sky 9 helicopter showed a swarm of LAPD vehicles in East 4 and Anderson in Los Angeles, with some red and blue lights flashing, as well as other private vehicles.

Law enforcement sources told CBS News that people were also aiming lasers at the authorities and that the LAPD had set up a confrontation line. At least one person, not an officer, was injured and his head was injured.

Officials say

Arriving by phone early Sunday morning, LAPD public information officer Cruz confirmed to Fox News Digital that an incident occurred at 1:46 a.m. in the East 4th and Anderson St. area where authorities responded to several radio calls regarding a “street takeover.”

Cruz said 50 to 60 vehicles are blocking the road and presenting donuts. Eventually the crowd dispersed and the area was declared safe, Cruz added, adding that he did not immediately have information that firecrackers or other missiles were fired at officers at the scene.
