Mustafa Ameen, better known by his internet nickname - "The Mystery Man" - has spoken out on his personal Facebook account. Ameen is now in the center of a post-fight scandal that revolves around last month's Amir Khan vs. Lamont Peterson encounter. Ameen denied allegations that he tried to affect the outcome of the Khan-Peterson bout, by distracting officials and allegedly touching score slips.

Last Thursday, Khan used his Twitter account to post a series of images of the man, seen wearing a dark hat. Using images and video, Khan detailed how Ameen was moving around the judges' table during the December fight in Washington, where Peterson won Khan's IBF and World Boxing Association titles after a controversial split decision.

"So you are questioning if I did something to harm my Muslim brother? May almighty Allah protect me from what you and the rest of you assert. Don’t make assumptions based on allegations," Ameen wrote to his Facebook followers.

Meanwhile, Khan's trainer Freddie Roach claims claims to know Ameen quite well. The veteran trainer disputes widespread reports that Ameen is affiliated with the International Boxing Federation.

Richard Schaefer, CEO of Golden Boy Promotions, was told Ameen was an IBF official who was given accreditation for the fight despite not being directly involved in it.

However, Roach says he personally knows Ameen and that he had no need to be ringside.

"He comes to my gym," Roach told BBC Sport. "He came to the [US] Olympic training centre and I actually had him removed one time. I told the coaches, 'There's no need for him to be here'. He goes to gyms and talks to other people's fighters.

"But he does know the boundaries because he doesn't go after my fighters - but he does talk to other people's fighters and he's been told not to a couple of times, even here in my gym."

Roach continued: "[Ameen] has no credentials; he's not a member of any boxing organization. There's no reason for him to be at ringside. Why he was ringside and why he was in the ring afterwards celebrating and so forth I have no idea."

Schaefer says the WBA will officially order Khan a rematch with the Peterson in the coming days, and urged the IBF to follow suit.

Roach agrees that, because of the possible interference, the fight should be declared a no contest and a rematch held.

He added: "You've got a guy sitting beside [Michael Welsh, World Boxing Association supervisor] that's talking about who's winning rounds and so forth - we can only speculate on what they were talking about but most likely they are talking about the fight.

"And people get influenced by other people easily. And that's why the rules are that no-one but officials are at ringside."
