Terrorist trained to be a security guard ahead of Olympics On his return to the UK small traces of explosive materials were found inside his bag at Heathrow airport - suggesting the rucksack had been used to carry them previously. He was not arrested but allowed to go through and put under surveillance. He first met Dart two months later and is said to have given him advice on who to contact out in Pakistan for terror training. Mrs Sultana said she had believed her son, who has a twin brother, had first met Dart at a local job centre and the latter was helping him find a wife. "It was a complete shock to later hear he had been accused of terrorism," she said. As far as I knew he was in Pakistan to see family. When he was young he was always in trouble with the police and I could not cope with him. It was never anything serious though. She said when he returned from Pakistan he was looking for work and job centre staff later suggested he train to be a security guard. He did a course and has just passed it when he was arrested. I don't know if it had anything to do with that because the Olympics were coming up. I don't even know if he was planning to try and get a job working there.
