Denise Richards gets note nailed with knife outside house

Los Angeles: Actor Charlie Sheen`s ex-wife Denise Richards and their daughters Sam and Lola found a threatening note and a knife outside their home after he blasted Sam`s school on Twitter for bullying.

The `Anger Management` star, who recently said his nine-year-old daughter, Sam, was bullied out of Viewpoint School in Calabasas, California, encouraged his Twitter followers to smear the campus with "rotted egg, a roll of toilet paper, or some dog poop". The 49-year-old blames the supporters of the school of leaving a threatening note and a knife jammed into a tree outside Richards` home, reported TMZ Online. "They had the pleasure of discovering a steak knife used to nail a note to the tree. Here`s why people suck; a group of mindless Viewpoint School supporting doosh-bagz have targeted Denise and the girls with `bullying tactics` as a response to my call to arms." He also urged people to leave his family alone, writing, "Leave them alone. This is not a threat but a promise that justice will be served. I`m not hiding. You are. Show yourselves you spineless cowards. Oh that`s right; cockroaches scatter in the light." Sheen said two people were captured on surveillance tape outside the property leaving the note and the knife and he has contacted police to investigate the alleged threat. PTI
