OAKLAND, California  - Several people were shot and a number of them killed Monday at a religious school outside San Francisco, local media reported, while police said a suspected gunman had been arrested.

The San Francisco Chronicle reported that four bodies were covered with tarps outside the Oikos University in East Oakland, while the Contra Costa Times reported a number of possible dead. Initially police warned that a suspect, described as Korean and in his 40s, was at large, but a short time later, the Oakland Police Department said on Twitter that they had a “possible suspect in custody.” “No imminent public safety threat appears to exist in immediate area,” it added. Five ambulances were dispatched to a “multi-patient medical scene,” the Oakland Fire Department said on its Twitter feed, citing reports of “multiple stabbing/gunshot victims.” The Oakland Police Department had tweeted that the suspect was “male, Asian, heavy build, khaki clothing, near or in area.”
