Sheen says his 9-year-old daughter Sam was bullied out of Viewpoint School and called a liar.
He Tweeted, "This is a legitimate call to arms ... If you have a rotted egg, a roll of toilet paper or some dog [expletive] I urge u to deliver it with 'extreme prejudice.'"
The school says Sheen's daughter has not been enrolled since March 2012. In a statement, the school said, "Viewpoint School first became aware of these accusations last year. Our administrators addressed the issue appropriately at that time. Our school take accusations of bullying very seriously. For over 50 years, Viewpoint School has provided a safe and nurturing environment for our students to thrive, and we will continue to do so."
Viewpoint went on to say that officials are concerned when any individual uses social medial to encourage actions that may risk the safety and security of any school.
