Authorities say there were at least five attacks on red-haired students at a Southern California middle school after a Facebook group announced "Kick a Ginger Day".
However, nobody was seriously hurt and no arrests were made.
A 12-year-old boy reported being kicked and hit by classmates at a middle school in Calabasas.
A sixth-grade girl told KABC-TV that some fellow students kicked her in the legs from behind.
Los Angeles County sheriff's Sgt. Fray Lupian says there were at least five victims.
Investigators say the Facebook message may have been inspired by a South Park TV episode that satirised racial prejudice by portraying a campaign against red-haired, fair-skinned "ginger" people.
