A man was shot and killed by deputies in Long Beach after allegedly ramming their patrol car and then charging at them with a knife Tuesday night, authorities said.

The incident unfolded around 9:20 p.m. when authorities received a call from a woman in the nearby City of Paramount who said the father of her children, who she thought was drunk, had violated a restraining order by coming to her home.

Deputies located a man matching the suspect’s description, seemingly still intoxicated, a few minutes later at the intersection of East Artesia Boulevard and Downey Avenue, a Los Angeles County Sheriff’s Department spokesperson told KTLA.

“Additional units were summoned to the area to try to initiate a traffic stop on the individual,” Lt. Michael Gomez said.

Instead of complying, the suspect apparently put his vehicle in reverse and crashed into a patrol unit at a high rate of speed.

“Subsequently, as they were giving him commands … He exited the vehicle with a knife in hand at which point he charged toward deputies and the deputy-involved shooting occurred,” Gomez said.

The suspect, whose name was not immediately released, was pronounced dead at the scene.

Video showed what appeared to be the suspect’s car next to a black canopy that was set up by authorities after the shooting.

A deputy who was injured during the incident was taken to a local hospital where they were treated and released
