Video of an Ohio gay teen being beaten was caught on video and posted on Facebook.

The video, captured by another another student with a cell phone, shows a teen waiting for his victim in a classroom at Union-Scioto High School in Chillicothe, approximately an hour south of Columbus. When the unnamed teen arrives, he is repeatedly beaten as other students watch.

The boy's mother, Rebecca Collins, told Columbus-based Fox affiliate WTTE that her son was being bullied because he's gay.

“It turns my stomach,” Collins said. “They did it just because he's a homosexual.”

The teen said nobody came to his defense – “He just kept hitting me and nobody did anything” – and that the bully had harassed him in the past, writing on the teen's Facebook photo just two days earlier, “Hey fag, check out the definition of a fag.”

Collins said her son suffered a possible concussion and a chipped tooth.

The bully received a three-day suspension. Collins said she's pursuing filing charges. (The video is embedded in the right panel of this page.)

Gay rights group Equality Ohio told gay blog that Union-Scioto has no policy in place that protects students based on sexual orientation or gender identity.

“All students, regardless of their sexual orientation or gender identity, have the right to a safe school and education,” said Equality Ohio Executive Director Ed Mullen. “Students should not fear verbal harassment, cyber-bullying or physical assault in our public schools.”
