A number of people have been killed and several injured in a shooting at a university in California, police say.

TV footage showed wounded people emerging from buildings at Oikos University in the city of Oakland.

Police and armed response teams surrounded the buildings, and a suspect was detained. A nearby hospital said it was treating four victims.
Oikos University is a private religious institution offering courses in theology, music and nursing.
Larry Reid, Oakland City Council President, told US media that six people had been killed and three wounded in the shooting.

Meanwhile, what appeared to be four bodies were seen outside a university building covered with tarpaulin, the San Francisco Chronicle reported.

Johnna Watson, of Oakland Police, said: “We know this to be a Korean college. A gunman came in to the college and fired multiple shots.

“We do have fatalities,  I cannot confirm the number of fatalities we have at this time. We additionally have victims who have suffered from gunshot wounds."
Ms Watson added that medical services as well as police were at the scene.

A suspect was taken into custody at a shopping centre in the nearby city of Alameda, officials told a local TV station.

The Oakland Fire Department says it was first notified of the shooting at about 10:50 local time (18:50 GMT).
Pastor Jong Kim, who founded the school about 10 years ago, told the Oakland Tribune that he heard about 30 gunshots in the building.

"I stayed in my office," he said.

A witness, Brian Snow, told local news station KGO-TV: “One of the people who was inside the building, she was saying there is a crazy guy inside.

"She did say someone got shot in the chest right next to her before she got taken off in an ambulance."
A woman who was doing errands nearby, Angie Johnson, told the San Francisco Chronicle she helped a woman with a gunshot wound in her arm.

The woman "had a hole in her right arm the size of a silver dollar with blood coming down", Ms Johnson told the newspaper.

Ms Johnson also said that, according to the woman, the gunman had stood up during a nursing class, shot one student in the chest at point blank range and then began firing at the rest of the room.

A police officer at the scene told reporters the gunman had not been identified.
Reports described the suspect as a Korean man in his 40s, with heavy build and wearing khaki clothes.
