A Saudi Arabian accused of associating with several of the September 11 hijackers and who disappeared from his home in the United States a few weeks before the attacks on the World Trade Centre and the Pentagon, is in London working for his country's state oil company. Abdulaziz al-Hijji ... flew to Saudi Arabia in August 2001. Security records of cars passing through a checkpoint at the Prestancia gated community indicated that Mr al-Hijji's home, 4224 Escondito Circle, had been visited a number of times by Mohamed Atta, the leader of the 19-strong hijack team, who piloted American Airlines Flight 11 into the North Tower of the World Trade Centre in 2001. The logs also indicated that Marwan Al-Shehhi, who crashed United Airlines Flight 175 into the South Tower, and Ziad Jarrah, who was at the controls of United Airlines Flight 93 when it crashed in a field in Pennsylvania, had visited the house. All three men had trained to fly at Venice Airport, which is 19 miles from Sarasota. Mr al-Hijji is resident in London, working for the European subsidiary of Saudi Aramco, Saudi Arabia's state oil company. Described as a career counsellor, he is based in the offices of Aramco Overseas Company UK Limited and lives in an expensive flat in central London.
