One person was killed and another injured Wednesday following a shooting inside a Muni train in San Francisco, California, police said.

San Francisco police responded to the shooting report at the Muni Forest Hill station and found that the train had left for Castro station, where officers discovered the two victims.

One was pronounced dead on the scene, and the other was taken to San Francisco General Hospital with non-life-threatening injuries, a police spokesperson said.

The shooter ran out of the train at Castro and was still at large, the police said.

The shooting was not random, according to a report by the San Francisco Chronicle which said the suspected shooter and one of the victims were in dispute before the gunfire.

"It's another reminder that as long as our country is awash in guns, shootings can happen anywhere, anytime," State Senator Scott Wiener said in a statement. "California has the strongest gun safety laws in the nation, and we're continuing to strengthen them. But we need strong action from Congress to truly improve the safety of our community."
