Los Angeles, March 20: Hollywood actor Charlie Sheen claimed his ex-wife Denise Richards and their daughters Sam and Lola found a threatening note and a knife outside their home.
The objects were found soon after the 47-year-old blasted a known children's school for allegedly allowing Sam to be bullied.
"My daughters had the pleasure of discovering a knife," contactmusic.com quoted Sheen as saying.
Sheen replied to the post that he tweeted a few days back. The post reads: "Here's why people suck, a group of mindless people have targeted Richards and the girls with bullying tactics as a response to my call to arms."
He also urged people to leave his family alone.
"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," said Sheen.
Sheen said two people were captured on surveillance tape outside the property and he has contacted police to investigate the alleged threat.
The school denied his claims and insisted they did everything necessary to deal with the situation.
