Police are investigating after a KnokX Pro Wrestling event was interrupted by the son of former UFC champion Quinton 'Rampage' Jackson.
The live stream appeared to show Raja Jackson slamming Stuart 'Syko Stu' Smith into the mat before punching his prone form several times, causing an injury.
Other wrestlers entered the ring and dragged Raja Jackson away from Syko Stu, with the prone man not getting up while onlookers called on someone to 'stop this s**t, man'.

Several wrestlers forced Raja into a corner and the LAPD have confirmed to the New York Times they are investigating the matter but would not comment further.
One of the wrestlers who intervened, Douglas Malo, told USA Today that Skyo Stu was awake and able to speak as of yesterday (24 August) but had lost 'a lot of teeth' and had broken bones in his face.

"He was choking on his own blood and teeth, somebody reminded me there's kids there and then I was like 'oh my God'," Malo said.
Stu's brother Andrew said he was 'stable but in critical care'.

On the live stream leading up to the incident Smith had hit Jackson with a beer can before being told that the son of the former UFC champion is not a wrestler.
After apologies they shake hands and agree that Jackson can be part of the upcoming wrestling match, with Raja being told to 'give him his receipt', a wrestling term about getting your own back on someone who got you.
"As long as I get my lick back, I'm straight," Jackson said on the live stream, he also said: "They told me to hit him and just leave, someone will pull me off of him and we'll leave. I'm telling you I'm gonna hit him as many times as I can, watch."
He entered the ring over an hour after the initial incident, picked Smith up and slammed him into the mat before repeatedly punching him in the face.
Quinton 'Rampage' Jackson said on social media that his son 'was told that he could get his 'payback' in the ring' and he thought what happened on the live stream was part of the show.
He said Raja 'had no business involved in an event like this' and he didn't condone his son's actions.

In a statement posted to social media, KnokX Pro Wrestling Academy made an apology to fans and said their main priority was the well being of Syko Stu.
They said: "First and foremost our thoughts and prayers are with our brother Mr. Stuart Smith (Syko Stu) as he remains a priority and we are monitoring his well being.
"What was supposed to be a planned and agreed upon wrestling spot, turned into a selfish, irresponsible act of violence against Mr. Smith. This egregious act is reprehensible and never should have occurred.
"In the 17 years of operation of KnokX Pro Wrestling Academy, there has never been anything as heinous take place such as this and we apologize to our patrons and fans."
