A middle school in Tacoma, Washington, has expelled nine students after catching them brawling in the boys' bathroom as a part of an organized fight club, inspired by the film of the same name.
The school became aware of the club after one of the boys' aunts found fight footage on her nephew's cellphone and turned it over to Fox News in Seattle.
About 23 boys appeared in the video, many of them gathered to watch. The school has said it will dole out punishment on a case-by-case basis for those not already expelled.
"This particular bathroom that was identified will be locked immediately after school and no longer accessible and we will be patrolling the grounds more vigilantly at school," Dan Voelpel of Tacoma Public Schools told Fox.
This isn't the first time David Fincher's 1999 film has inspired copycat violence. In 2006, police in Newfoundland and Labrador broke up a fight club with about 150 teenage members in Corner Brook.
In May 2010, two men in their early twenties were stabbed at a fight club in Montebello, California.
