Being bullied at school is bad enough, but what is a child to do when the bullying follows you home? Charlie Sheen, 47, recently called out Viewpoint School on Twitter after they failed to do anything about the bullies targeting his daughter Sam, nine. The young girl has since left the school, but the bullying still continues. According to the former Two and a Half Men star, a knife with a threatening note was wedged into a tree outside the home of his ex-wife Denise Richards and their two daughters. Charlie took to Twitter once again to express his anger with those involved. “Leave them alone,” he tweeted. “This is not a threat but a promise that justice will be served. I’m not hiding. You are. Show yourselves you spineless cowards.” Luckily for the family one of the cameras located at the residence caught the culprits faces on camera, and the police are currently investigating the situation. ~Brittnee Fleming
