Here is the report from The Blast:
Blac Chyna called two of his friends on FaceTime and was playing with Rob’s gun, pointing the gun at the camera at one point.
Kardashian claims later in the evening, Chyna lunged towards him with an iPhone charging cable and attempted to strangle him with the cord. He claims he was able to get away from her, but she chased after him and repeatedly struck him in the head and face.
Rob claims he suffered injuries to his neck and documented the whole thing, including tears to his shirt around the collar.
Kardashian says Chyna then proceeded to trash the house – which he was renting from his sister, Kylie Jenner — damaging a television, breaking down a door, damaging the walls, destroying cell phones and smashing a gingerbread house that was made for the holidays.
