The Spanish intelligence agency CESID (later renamed CNI) frustrates the arrest of a senior member of al-Qaeda in Europe, Amer el-Azizi, by Spanish police. Most members of the cell of which el-Azizi was a member were arrested shortly before, but el-Azizi had avoided the round-up by fleeing abroad (see October 2001). After returning to Spain, he again falls under police surveillance, but, according to Spanish police union head Jose Manuel Sanchez Fornet, his arrest is prevented by “interference” from CESID. Fornet will later say that a police recording made at this time shows two CESID agents going to el-Azizi’s house. This alerts el-Azizi that he is under surveillance and he flees his home. [El Mundo (Madrid), 4/29/2004] El-Azizi then remains in Spain for some weeks, selling his car to an associate. When his apartment is searched, police find more than a dozen bags with radical Islamic books and videos. They also find videos of bin Laden on his computer and pamphlets from groups like Hamas. [Wall Street Journal, 3/19/2004; Wall Street Journal, 4/7/2004; Los Angeles Times, 4/29/2004] El-Azizi was arrested and released twice before (see October 10, 2000). He helped plan a meeting for Mohamed Atta just before 9/11 (see Before July 8, 2001 and July 8-19, 2001), and will go on to be involved in the Madrid train bombings (see Before March 11, 2004 and 7:37-7:42 a.m., March 11, 2004).
