[5] Abu Izzadeen is a British citizen born on 18 April 1975 in Hackney, east London, to a Christian[6] family originally from Jamaica.
Brooks converted to Islam the day before he turned 18, on 17 April 1993, changing his name to Omar, but preferring to be called Abu Izzadeen.
[12] On 20 September 2006, Abu Izzadeen and Anjem Choudary disrupted Home Secretary John Reid's first public meeting with Muslims since his appointment.
In a heated discussion Abu Izzadeen stated that his aim was to bring about Sharia law in the UK and that this should be achieved without following the democratic process but rather "in accordance to the Islamic methodology".
A spokesman for Scotland Yard said the arrest is related to an "on-going inquiry," involving a speech Abu Izadeen gave in the West Midlands area in 2006, which predates 20 September 2006 incident.
On 14 November 2015, Izzadeen and Sulayman Keeler were detained by police in Lőkösháza, Hungary, on a train heading to Bucharest, Romania, because they were not able to identify themselves.
