Los Angeles police are investigating a case involving Raja Jackson, son of ex-UFC champ Quinton "Rampage" Jackson, who is shown on video punching an apparently unconscious pro wrestler at least 20 times in the head.

Raja Jackson, the son of former UFC light heavyweight champion Quinton "Rampage" Jackson, appeared to brutally assault a professional wrestler at an independent wrestling event in California on Saturday.

Rampage Jackson apologized on social media on behalf of his son and said the incident was a miscommunication. He said his son was unexpectedly hit in the head moments before Smith's match and was told that he could get his "payback" in the ring as part of the show.
