LOS ANGELES — Authorities searched Sunday for a gunman who shot and critically wounded two Los Angeles County sheriff’s deputies who were sitting in their squad car — an apparent ambush that drew a reward for information and an angry response from the president.

The 31-year-old female deputy and 24-year-old male deputy underwent surgery Saturday evening, Sheriff Alex Villanueva said in a late-night news conference. Both graduated from the academy 14 months ago, he said.

They were each in critical condition Sunday afternoon, said Deputy Trina Schrader.

The deputies were shot while sitting in their patrol car at a Metro rail station and were able to radio for help, the sheriff said. Villanueva, whose department has been criticized during recent protests over racial unrest, expressed frustration over anti-police sentiment as he urged people to pray for the deputies.

The department tweeted video of the shooting that shows a person approach the parked patrol car on foot and shoot through the passenger-side window.

“The gunman walked up on the deputies and opened fire without warning or provocation,” the department stated.

An extended version of the video reviewed by the Los Angeles Times shows the shooter running away. He turns a corner out of the frame, past a second figure lingering on the sidewalk.

The video sparked reaction from President Trump who responded on Twitter, “Animals that must be hit hard!”

“This cold-blooded shooting is unconscionable and the perpetrator must be brought to justice,” Democratic presidential candidate Joe Biden tweeted.
