Washington: A domestic violence investigation has been opened in connection with Mel Gibson`s alleged attack on ex Oksana Grigorieva.
The LA County Sheriff`s Dept has released a statement claiming investigators are "currently gathering information regarding the allegations," reports TMZ.com.
The alleged incidents occurred in Malibu in both January and February of this year.
According to the sources, Gibson was violent toward her several times, the worst of which she claims occurred in January and February.
Grigorieva also told deputies she secretly tape recorded Gibson after the two worst violent episodes, because she feared for her safety.
