A high school student who was beaten in a videotaped assault in a campus restroom is suing the school district and eight people allegedly involved in the attack.

Hassan Rahgozar, 17, claims that administrators at Hercules Middle/High School maintained inadequate security and failed to protect him in the May 6 attack, which was viewed widely after being posted on the Internet.

Rahgozar, an Iranian-American, suffered a crushed jaw and two black eyes. The suit claims the attack was racially motivated.

The incident followed an April 29 attack on Rahgozar in a campus locker room.

The suit, filed in Contra Costa County Superior Court, claims that administrators with the West Contra Costa Unified School District were aware of the threats against Rahgozar but failed to protect him.

"It just really surprises me very much how badly the school district dropped the ball in this case," his lawyer, William Berg, said Monday, adding that Rahgozar is now being home-schooled. "It didn't take a fortune teller to see what was going to happen."

School district spokesman Paul Ehara declined to comment Tuesday.

In the videotaped beating, a 16-year-old boy who had previously been suspended for assaulting Rahgozar was seen punching him in the face repeatedly and calling him a snitch, police said. The boy acknowledged in juvenile court taking part in the attack and was expelled.

Another attacker, Eric Guillebeau, 18, was sentenced to a year in a jail and placed on three years' probation after pleading no contest earlier this year to battery. Guillebeau is a Sacramento resident who was not a student at the school.
