Charlie Sheen, ever reliable for batsh*ttery, still wants to throw dog poo at his daughter's old school.

Sheen claimed his nine-year-old daughter, Sam, was 'bullied out' of Viewpoint School in Calabasas, California and encouraged his Twitter followers to take a stand by smearing 'rotted egg, a roll of toilet paper, or some dog s**t there.'

A spokesperson for the school denied the actor's claim officials had called Sam a liar and tried to bury the problem, but Charlie has hit back, saying they 'should be ashamed of itself for allowing the bullying to go on and try to hide it'.

He added to TMZ: 'They needed a visual reminder not to forget the epidemic of bullying... There's no statute of limitations on bullying.'

Sam, whose mother is actress Denise Richards, was forced to leave her school in March 2012 and erratic father-of-five Charlie has no regrets about targeting a nine-year-old girl called Victoria - whom he believes is responsible for the bullying - during his Twitter tirade, as he wants to give her a taste of her own medicine.

He told website TMZ: '[So what if she is a] Nine-year-old! How about the Nine-year-old who is harmless and sweet and was just trying to make a friend.'

Charlie had previously outed Victoria in his online rant, writing: 'And if your feeling the 'show and tell' of it all, smear the s**t to spell one name on the front door; VICTORIA. eat that loser. C'

The school has allegedly increased security following Charlie's 'call to arms' and a police car has been spotted outside.
