RadarOnline.com has a slew of new details on Mel Gibson’s alleged assault of ex-girlfriend Oksana Grigorieva—and her allegations include that Gibson threatened to kill her, her children, and himself. Grigorieva says Gibson was furious at her for attending her son’s basketball game while leaving their infant daughter at home with a nanny. She says that, when she got home, Gibson started screaming at her, then punched her and choked her in front of her children. Then Grigorieva claims he pulled a gun and threatened to kill everyone in the room, including himself. Grigorieva’s son Sascha, whose father is former James Bond star Timothy Dalton, was interviewed about the incident by child protective services on Friday.
