When confronted outside his family's £300,000 home in the affluent Heaton Mersey suburb of Stockport, Dr Mostafa insisted he had done nothing wrong - and thanked the Government for getting him back. "I'd like to thank the British authorities who have been very helpful and nice," he said. "My arrest was politically motivated and part of the war against Islam."
Dr Mostafa, a father of three, has been linked to a series of terroristrelated offences in the last 14 years. In 1996 he was acquitted of planning to cause explosions with other Manchester University students, but found guilty of illegally possessing a firearm bought from a gangster in Moss Side and jailed for four years.
In 2000 he was charged with fellow Bangladeshi Moinul Abedin of planning to cause explosions after police in Birmingham recovered a large cache of chemicals and detonators. He was cleared when it was accepted he was planning to open a fireworks shop but Abedin was jailed for 20 years.
In 2008 Dr Mostafa was given a two-year suspended jail sentence and 100 hours' community service for trying to board a Bangladesh-bound plane at Manchester with a pistol and bullet parts in his suitcase.
