Charlie Sheen, formerly of the sitcom "Two and a Half Men", went on a rant on social networking site Twitter Thursday, claiming his daughter is being bullied at the Viewpoint School in Calabasas, Calif. and claiming that school officials are not doing anything about it.

"This is a legitimate call to arms," Sheen tweeted, "My daughter Sam was bullied out of Viewpoint School and then called a liar. it's on! if you have a rotted egg, a roll of toilet paper, or some dog s---; I urge u to deliver it with 'extreme prejudice' to their KamPuss run by trolls and charlatans. make me proud. We will not tolerate this level of abhorrent disrespect towards the child of your favorite Warlock."

Sam, Sheen's 9-year-old child with ex-wife Denise Richards, was teased mercilessly about her skin, looks, hair, and even Charlie getting fired from "Two and a Half Men" at her private school, TMZ reported.

"Viewpoint School's highest priority is the safety, security and education of our students," read an apparent response to Sheen's rant on the private school's Facebook page.

"Like all responsible schools across our nation, we are concerned when any individual uses a social media forum to encourage actions that may risk the safety and security of any school. The parent of a former Viewpoint School student who has not attended Viewpoint School since March 2012 has made certain accusations in the media. Viewpoint School first became aware of these accusations last year. Our administrators addressed the issue appropriately at that time. Our School takes accusations of bullying very seriously."
