A 17-year-old male who was hospitalized with life-threatening injuries after being shot by BART police at the El Cerrito del Norte station on Saturday afternoon is expected to survive, the transit district said Sunday morning.

The suspect's gun was also recovered, police said.

Saturday's shooting took place around 2 p.m. when officers responded to a domestic disturbance on a BART train. Witnesses reported a verbal argument between a man and a woman, and said that the young man had a gun in his waistband.

Two officers approached the suspect, who ran off the train and onto the platform at the El Cerrito del Norte Station. The suspect then ran onto the tracks.

A suspect was wounded in an officer-involved shooting Saturday afternoon at the El Cerrito del Norte Station, BART officials said. The incident started as a domestic dispute between what witnesses said was a man and a woman and ended after the man produced a gun, prompting officers to shoot, authorities said.

"Officers got onto the platform, challenged that individual who ran off the train, down the platform and onto our trackway," said BART Police Cheif Ed Alvarez. "At this point a gun was produced and our officers ultimately shot."

Officials said that it is not yet known how many shots were fired.

The suspect sustained life-threatening injuries and was transported to a hospital, police said.

"I thought it sounded like M-80s or something you hear on Halloween, like eight or 9 in a row," said Dan Holzman, a witness. "All of a sudden people started running out, I was like, that's gotta be gunshots with people running out like that."

The woman involved was unharmed.

BART police are reviewing video from the platform, body cameras and the train.

The Del Norte and Richmond stations were closed until after 10 p.m. Saturday in the aftermath of the incident.

This officer-involved shooting comes on the first weekend of BART's new safety plan. A 12-person unarmed patrol called BART ambassadors will be riding trains and walking platforms.

BART has seen ridership plummet during off-peak hours and weekends over the last few years.
