Hogan, real name Terry Bollea, was fired by bosses at World Wrestling Entertainment (WWE) on Friday (24Jul15) after the audio tape, in which he was commenting on his daughter Brooke's love life, was made public.

Bollea has since admitted the voice on the tape does belong to him and he has issued an apology for his actions.

A statement issued to Us Weekly magazine reads, "Eight years ago I used offensive language during a conversation.

"It was unacceptable for me to have used that offensive language; there is no excuse for it; and I apologize for having done it.

"I believe very strongly that every person in the world is important and should not be treated differently based on race, gender, orientation, religious beliefs or otherwise. I am disappointed with myself that I used language that is offensive and inconsistent with my own beliefs. It is not who I am. I continue to work every day to improve as a person, and this matter is an important learning experience for me in that regard. As a result, I am resigning from my contractual relationship with the WWE."

The tape comes ahead of a legal case brought by Hogan against bosses at media company Gawker, who have allegedly uncovered further audio footage of Hogan using a derogatory slur several times. He is currently suing the publication for allegedly releasing a sex tape of his without permission.

Meanwhile, Hogan's lawyer, David Houston reveals they are currently investigating who leaked the tape.

He says, "Hulk has apologised to all of his fans and we can only ask for forgiveness and understanding at this point."

He adds, "We are investigating who leaked this audio and again, it is an especially suspicious circumstance realising we are in a very contentious litigation with Gawker media. This tape surfaces through a transcript with National Enquirer at a time, when quite frankly some would say certain people would do anything. And as a consequence of this leak, we will do all possible to investigate who is responsible and who again, after three years has passed, is once again attempting to attack Mr. Bollea and successfully sell."

WWE bosses, who have since scrubbed Hogan's name from their Hall of Fame records, maintain the wrestler was fired before he could resign.
