In March 2003, the British domestic intelligence agency MI5 arrests eight members of the Islamist militant group Al-Muhajiroun in the city of Derby. Two other Britons, Asif Hanif and Omar Sharif, are also identified as members of the group, but they are not arrested. MI5 is also aware that Sharif is connected to the Finsbury Park mosque where radical imam Abu Hamza al-Masri preaches. [Daily Mail, 5/5/2003; ISN Security Watch, 7/21/2005] When police raided Abu Hamza’s mosque in January, they even found a letter from Sharif to Abu Hamza inquiring about the proper conduct of jihad. The letter contained Sharif’s address in Derby. [O’Neill and McGrory, 2006, pp. 90-91] MI5 does not monitor either Hanif or Sharif, and instead simply keeps their names on file, believing them to be harmless. Later that same month, Italian undercover journalist Claudio Franco, posing as a Muslim convert, visits the London office of Al-Muhajiroun and meets Hanif. Hanif, unaware that he is being formally interviewed, tells Franco that he is sorry the poison ricin was allegedly seized in a raid elsewhere in London (see January 7, 2003) before it could be used in an attack. The next month, Hanif and Sharif travel to Israel and are killed on a suicide bombing mission which kills three others (see April 30, 2003). After the bombing, Al-Muhajiroun’s official leader, Anjem Choudary, calls the two bombers martyrs. The group’s spiritual leader, Sheikh Omar Bakri Mohammed, admits he knew both men. But the group is not banned. [Daily Mail, 5/5/2003; ISN Security Watch, 7/21/2005] Other members of the group will attempt to build a large fertilizer bomb in early 2004 (see Early 2003-April 6, 2004), but the group will still not be banned, then or later. (It will disband on its own in late 2004 (see October 2004).) Investigators also fail to discover that Mohammad Sidique Khan, the lead bomber in the 7/7 London bombings (see July 7, 2005), knew both men, was friends with Sharif and attended the same small mosque as he did (see Summer 2001), and traveled to Israel weeks before they did in a probable attempt to help with the bombing (see February 19-20, 2003).
