Omar Brooks, who hit the headlines earlier this year when he was labelled 'Britain's new number one hate preacher', started life in a radically different guise.
Mr Brooks - or Abu Izzadeen, as he is now more commonly known - was born into a Christian family of Jamaican origin in Hackney, East London, and was known as Trevor to some acquaintances.
He converted to Islam at the age of 17 and is believed to have become involved with Omar Bakri Mohammed at Finsbury Park Mosque in the late 1990s.
He trained and worked as an electrician and his new name - Abu Izzadeen - means 'Might of the Faith' in Arabic.
He is thought to have become the new Emir of the Saved or Saviour Sect, regularly posting his sermons onto the group's website.
The Saviour Sect wants Britain to adopt Islamic law and has links with al-Ghurabaa, whose leader was arrested during extremist protests against the publication of cartoons depicting the Prophet Mohammed. Abu Izzadeen has also been touted as the leader of al-Ghurabaa.
Over the past couple of years he has made a series of inflammatory statements which have been widely reported.
During lectures in March, entitled The Christian Crusades parts one and two, he was reported as saying that a war was being fought to make Islamic law "completely dominant" in Britain, and that "all Jews and Christians are going to hell fire".
On the BBC's News-night last year he said that the July 7 bombings would make people "wake up and smell the coffee".
He said of the London bombings: "I would never denounce the bombings, even if my own family was to suffer, because we always stand with the Muslims, regardless of the consequences."
The CPS was considering charges against Izzadeen for solicitation to murder and withholding information about terrorism. He is married with three children and lives on benefits in Leyton, London. ..SUPL:
