London, Jan 19 (IANS) The Los Angeles deputy district attorney’s office is reportedly preparing to file criminal charges against actor Mel Gibson for allegedly hitting his ex-girlfriend Oksana Grigorieva.

Femalefirst.co.uk reports that there is a strong case to support filing criminal charges against Gibson.

Despite the actor-director’s lawyer Blair Berk’s meeting with Los Angeles deputy district attorney John Lynch for close to two hours to persuade them otherwise, it is thought the office will bring charges against him for assaulting his former girlfriend Jan 6 last year.

The charge is likely to be violence or corporal injury involving a former cohabitant, which can be prosecuted as either a felony or misdemeanour.

‘Blair is aware that the District Attorney is inclined to file charges against Mel,’ a source told RadarOnline.com.

‘The District Attorney (DA) has a very strong case, there is a lot of information that the public and Mel Gibson are unaware that the DA has.’

Grigorieva, 40, has claimed Gibson, 55, punched her in the head at his Malibu home, which knocked two veneers out from her upper front teeth while she held their daughter Lucia, now 15 months.

While Gibson has confessed in a written declaration that he slapped her during an argument because she was hysterical, he denies hitting her.
