One person dead, 14 injured in US school shooting

One person has died and 14 people have been injured when a gunman opened fire on fellow students at Californian school.

A policeman and a school administrator are believed to be among those wounded in the incident at Santana High School in Santee, San Diego.

One man, believed to be a 17-year-old first year student at the school, has been arrested.

Witnesses say he used a small handgun and fired several shots in the boys' changing room area of the school and hallway.

One student said the youth smiled as he fired a long-barrelled handgun.

Witnesses say the teenager had bragged to fellow students about having a gun and had previously made threats about carrying out a shooting.

"I heard gunfire and I heard people screaming," student Alicia Zimmer told local TV station KGTV.

She said she froze with fright until her boyfriend pushed her out of the way: "I dropped my stuff; it's still there right in the middle of the hall. It was really scary."

She said she did not see the gun but witnessed one girl with blood on her arm and a boy lying face down on the floor.

The shots "sounded more like a cap gun than anything," she said.
