Investigators from the Department of Children and Family Services visited the home of Oksana Grigorieva on Friday to question her son Alexander.
RadarOnline.com learned exclusively that her 12-year-old son witnessed the violent confrontation that allegedly occurred between Oksana and Mel Gibson on January 6 – chipping one of Oksana’s front teeth and knocking the veneer off another.
The video shows at least four people showing up to Oksana’s house on Friday, and Oksana lets two of them in though the side gate.
Investigators were led to probe the January 6 incident after RadarOnline.com released audio between Mel and Oksana in which he admits hitting her saying, “You f**king deserved it!”
In another of the taped conversations, an out-of-control Mel is heard yelling: “You need a f**king bat in the side of the head.”
Mel has adamantly denied through his representatives ever physically harming Oksana and insists she has provided zero evidence to support her claim that Mel caused the damage to her teeth.
