Johnny Depp grabbed his then-wife Amber Heard by the hair and repeatedly struck her in the face during a heated argument about a month after their marriage, her sister said Wednesday.

Henriquez said Depp's bodyguard moved to intervene, "but by that time Johnny had already grabbed Amber by the hair with one hand and was whacking her repeatedly in the face with the other."
