The mother of a Saskatoon teenager has gone to the police after seeing her son beaten up in a YouTube fight video.

Amateur fight videos involving teenagers or young men have become increasingly popular on the internet, and when Brenda Burns saw her son in one of them, she was appalled.

One YouTube video shows Burns's 16-year-old son, Jonathon Carroll, falling to the ground and being kicked in the head by another teenager.

Burns said her son joined a fight club called "No Quitters" because he wanted to be accepted at his new high school.

"Just pretty much 15 minutes of fame thing on video," Carroll said.

However, after a couple of fights, the fame wasn't worth the pain, said Carroll, a Grade 10 student at Aden Bowman Collegiate in Saskatoon.

"It got carried away," he said. "When I was on the ground in the fetal position, the guy kicked me in the back of the head near my neck. That could have killed me."

Burns said her son was coming home with massive bruises.

"Black and blue bruises on his arms," she said. "Another time he came home with lumps on his head."

Until recently, Burns hadn't seen any of the videos. When she did, she was disgusted, she said.

"I'm nauseous," she said. "There are no words to really describe it."

Insp. Rick Penny of the Saskatoon police service said he wants to stop the behaviour before it has a chance to escalate.

"What initially starts off with a couple of young people as a prank sometimes goes too far," he said. "If in fact there was injury caused, then it becomes a crime."

It will take about a month to investigate the fight club and make a decision about charges, Penny said.
