COMPTON, California—Officials say two Los Angeles County sheriff’s deputies were shot Saturday without provocation while sitting in their patrol car at a Metro rail station in what appeared to be an ambush.

The sheriff’s department said a 24-year-old male deputy and a 31-year-old female deputy were shot in the head and had multiple gunshot wounds. They are in critical condition and have undergone surgery.

“The gunman walked up on the deputies and opened fire without warning or provocation,” the sheriff’s department said in a Twitter post that included video showing a person open fire through the passenger-side window of the patrol car.

The incident happened around 7 p.m. a short distance from the Compton sheriff’s station. The suspect is still at large.

Assemblymember Reggie Jones-Sawyer, who is the chair of public safety for California state, told a press conference, “This was an unprovoked, cowardly act. The individual will be caught and justice will prevail. Our society must not tolerate such acts of violence.

“Tonight, we must as a community must condemn the actions of the perpetrators, but most importantly, we must all come together, pray together for these officers because they are heroes,” he added.
