Nazamuddin Mohammidy was one of nine Afghans who took over the Afghan airliner in 2000. The plane was flown to Stansted, where the hijackers demanded asylum in Britain in exchange for the lives of the 160 passengers. They were given the right to remain in Britain after a stint in jail.
Police became suspicious of Mohammidy after they saw him driving around Terminal 5. When they stopped him, they were shocked to find that he works for a contractor who is entrusted with cleaning the offices at Heathrow. Mohammidy was also in breach of bail over an assault case.
