Mustafa Ameen has vowed to sue former light-welterweight world champion Amir Khan unless he apologizes for comments relating to his role in December's fight against Lamont Peterson.

Bolton fighter Khan lost his WBA and IBF belts to local man Peterson in Washington DC on December 10 in a disputed split decision defeat.

Since then he has raised a number of grievances, the most recent of which was asking what Ameen - at that point an unidentified 'mystery man' - was doing at ringside interacting with WBA supervisor Michael Welsh.

It has since come to light that Ameen is loosely affiliated to the IBF (International Boxing Federation) but had no official business on the night, with the body later stating "he is not an employee or an official of the organisation" and that he "was not assigned by the IBF to officiate this bout".

Khan and his team have talked and tweeted tirelessly about his role in the saga and after Wednesday's IBF hearing - which he was due to speak at - was cancelled at Khan's team's behest, Ameen has spoken out.

"Amir Khan is going to have to apologize because I am in the process...I will litigate this," he said.

"I am already in discussions with some of the most successful legal firms in Britain regarding the slander, the libellous statements that have been made against me by Amir Khan and other individuals in the press and I intend to fully seek a remedy in a court of law.

"I will give Mr Khan an opportunity prior to me reaching the point of no return of filing a lawsuit, he has an opportunity (to apologize).

"I understand maybe in the heat of the moment in his disappointment there were things that he tweeted.

"But if you look back at all of the things that have changed about the 'mystery man' and 'the man in the hat', then it comes out that I'm a charitable guy that works with distressed fighters on behalf of the IBF. I receive no remuneration. I actually spend my own money. I don't even ask them for reimbursement for expenses. I fly, I talk with them, there are no financial ties."

Ameen, speaking to Sky Sports News, added: "My life is clean. For Mr Khan to accuse me of the things that he has accused me of, and to have all of the sheep - the British sheep, the fans, the media, his team - for them to add on, they all piled on on Mustafa Ameen, but I'm still standing, I'm going to fight back. And Mr Khan needs to apologise, if not we will litigate this in court.

"I'm going to sue, yes. And he's not alone. As a matter of fact Mr Freddie Roach (Khan's trainer) has made some very libellous, slanderous statements that are obvious untruths.

"Mr Roach needs to apologize and if Mr Roach wants to issue an apology to me I will accept his apology - but it needs to be very, very soon because I'm in the process of sorting out which legal team I want to represent me.

"I'll guarantee you I will have the best legal team."
