Islamic preacher Hamza Andreas Tzortzis has been allegedly "named" on the leaked list of members of the adult website Ashley Madison. However, the well-known preacher has denied that the account belonged to him.

Tzortzis has also denied signing up for an account on Ashely Madison, the infidelity dating website -- which was recently attacked by hackers who leaked the names of hundreds of thousands of its members -- and said that it was a conspiracy by hackers to defame him.

Tzortzis, a member of the Islamic Education and Research Academy, is known for his radical Islamic views.

In a Facebook post, Tzortzis wrote: "It has come to my attention that my details are on the Ashley Madison data leak. This includes my name, address, and bank card details."

"This is an obvious case of fraud. My email address (this website doesn't verify emails, and all the relevant emails went to junk) can be found online and so can my address, as it is linked to my business account, which is registered online."

Tzortzis also said he has filed a formal complaint with the police over the hack of his bank details. He added: "I am not ruling anything out at the moment, including the possibility of my phone being illegally hacked. Retrospectively speaking, it has shown signs of being hacked.

"It seems that the first transaction was made in Australia when I was there for lectures and courses. It could have been someone who knows me, someone who hates me, or a malicious person who found out who I was. It could be one person or two, they could be working locally, from abroad or both," he wrote.

Tzortzis is known for his radical Islamic views and has openly expressed his stances on sexual morality and homosexuality. He was believed to have made several controversial remarks such as those who leave Islam "should be killed" and has voiced his support of setting up an Islamic Caliphate.
