Authorities are searching for a gunman who opened fire on the 5 Freeway, striking a driver in the chest near downtown Los Angeles late Thursday night.

The driver was headed northbound along the freeway near Calzona Street shortly before 11 p.m. when he saw the driver of a blue Chevrolet Trailblazer next to him suddenly fire two gunshots in his direction, according to California Highway Patrol.

The victim “felt pain to his chest” and got off the freeway before calling 911 for help, CHP officials said in a news release. 

The driver had suffered a gunshot wound to the chest and was taken to a local hospital, according to CHP Officer Kimbal. The wound was described as being not life-threatening and the man was listed in stable condition Tuesday. 

Officers went to the northbound 5 Freeway at Indiana Street in the Boyle Heights area to look for evidence connected to the car-to-car shooting, CHP told KTLA. It was unclear Tuesday morning whether anything was found at the scene.

Video showed Los Angeles Police Department officers searching a red sedan with a shattered passenger-side window.

Paramedics were seen transporting a man with a visible wound to his chest into an ambulance. The man appeared alert and was speaking with first responders.

Officials did not have a description of the gunman and it’s unclear what motivated the shooting.

No further details were immediately available.

Anyone with information is asked to contact California Highway Patrol at 213-744-2331 or 323-259-3200.
