Carroll had been visiting relatives in the area. A keen photographer, he had taken his camera with him on a Saturday morning shopping trip to take some shots of the high street. He was in Boots with his brother and sister-in-law when he was confronted by the police, who told him they had received a complaint from a member of the public that he had been taking pictures of 'sensitive buildings'. 'I was marched out of the shop, stood against the wall and made to empty my pockets,' he says. 'I was scared and intimidated. I mean, I'm one of the most law-abiding citizens you could meet. I don't even drop litter! I shouldn't really have handed over the film but, at the time, I was afraid of being arrested.'
The police had the film developed and returned the pictures to him later that day, acknowledging that they were entirely innocuous. They also admitted that there had been no complaint from the public; they had stopped Carroll because they thought he was taking pictures of children. Carroll lodged a complaint with the local station. 'The superintendent at Humberside police got in touch and was very sympathetic. But he still claimed that his officers had behaved correctly and at times of heightened security we have to accept less freedom for our own good.'
