Charlie Sheen is making a chilling new claim in his war against the school his daughter once attended.
He says two men left a threatening note pinned with a steak knife to a tree in his daughters' front yard.
Sheen said, "Sam and Lola had the displeasure of discovering a steak knife used to nail a note to the tree. We got a pretty good look at them from cameras and police are involved."
The incident allegedly happened at the home of Sheen's ex-wife, Denise Richards, who is raising their daughters, nine-year-old Sam and seven-year-old Lola.
Sheen says the threat is connected to his war of words with the Viewpoint School in Calabasas, California. He claimed Sam was bullied by another pupil, forcing him and Denise to pull Sam from the school.
Sheen last week called on his fans to deliver dog poop to the school as payback, although he now says he wasn't serious.
He said, "I wasn't expecting anyone to literally show up and do that."
Sheen told TMZ in a phone interview he'd return the steak knife to its owner, well, sort of.
He said, "I will return it through their heart, how about that?"
Meanwhile, two former Viewpoint pupils, Emily Kent and Alicia La Maina, are defending the school and blasting Sheen's vendetta.
"I feel badly for his child that got bullied, and it is not an okay situation. But his response is just facilitating the problem," said Kent.
La Maina said, "Charlie Sheen has a right to be upset, but I don't think that the actions he took, talking about the school and reacting on his Twitter posts is the right way to go about it."
