Investigators say seven California children had injuries consistent with abuse after attending a boot camp for at-risk youth last month.

Tony Cipolla, a spokesman for the San Luis Obispo Sheriff's Office, declined Wednesday to describe the children's injuries.

Greg Owen, an attorney representing the children's parents, says most had cuts and bruises and one had a fractured hand.

The parents say their children were punched, kicked and stomped on during the camp held in San Luis Obispo between May 17 and 24.

Cipolla says the sheriff's office is still interviewing 39 children who attended the boot camp and their drill instructors, all members of two Los Angeles-area police departments.

A spokesman for one of the police agencies says both are taking the allegations very seriously.
