(CNN)Police are hunting for a gunman who shot and killed a fellow passenger on board a train in Oakland, California.
The shooting occurred at 7:50 p.m. on Saturday as the Bay Area Rapid Transit train approached the West Oakland station, near the city's waterfront, BART spokesman Jim Allison said.
The shooter ran off the train and remains at large.
A doctor on board the train performed CPR at the scene, but was unable to save the victim, Allison said.
There were no details on what led to the shooting.
Allison said the train station was closed while police investigated and the cars had been removed from service to gather more evidence.
The suspect was wearing blue jeans, military-style boots and a dark jacket.
