Charlie Sheen has put the blame on the gas Nitrous Oxide for making him assaulting a dental technician.
The 49-year-old star is facing a lawsuit from Margarita Palestino, who claims that Sheen grabbed her boob and tried to attack her with a knife in October as he sat in a dental chair, TMZ.com reported.
She told the cops that the actor's bodyguard said that he was even high on rock cocaine at the time.
However, the 'Two And A Half Men' star and his team strongly denied the reports, saying that he was on medication for a shoulder injury and had an adverse reaction to the nitrous, causing him to flail around and accidentally knock over a tray of tools.
Sheen's lawyer said that the technician was fired for violating HIPAA laws by telling her son about the actor's presence in the office, and was now making up stories.
