SAN JOSE, Calif. (AP) — Caltrain officials say train service between San Francisco and San Francisco is back to normal after a shooting involving a San Mateo County sheriff's deputy.

Caltrain spokeswoman Christine Dunn says service was disrupted after the shooting around 5:30 p.m. Wednesday near the railroad's facilities in San Jose.

Dunn says regular service resumed by 8:40 p.m.

No additional information has been released about the shooting, but Dunn says the deputy involved is part of the Transit Police Bureau, a unit of the San Mateo County Sheriff's Department under contract to provide service for Caltrain and for SamTrans buses.
