Three boys have been arrested in connection with the so-called "ginger attacks," instigated by a Facebook message, in which at least seven red-haired children were beaten up at a Calabasas middle school, a sheriff's spokesman said this morning.

Two 12-year-old students at A.E. Wright Middle School were arrested on suspicion of battery on school property, and a 13-year-old boy was accused of threatening to inflict injury "by means of electronic communication."

"The charge against the 13-year-old male is commonly referred to as cyber-bullying, something that is occurring way too much," said Steve Whitmore, spokesman for the L.A. County Sheriff's Department.

The children were booked Wednesday before being released to the custody of their parents. No court date has been set for their initial appearance at Sylmar Juvenile Hall.

Sheriff’s detectives are continuing to investigate the assaults and have identified eight boys at the school as subjects of the investigation. Authorities believe the attacks were spurred by a Facebook message about “Kick a Ginger Day," inspired by the television show "South Park."
