7 July 2005 London bombings
The three arrested were thought to be friends of the bombers, living in the same area as them and going to the same mosque. They were put in court twice because of what they were thought to have done. This was because the jury in the first trial did not agree whether they were guilty or not. In the second trial, they were found to not have helped the bombers attack London, but the two arrested at the airport were later went to prison for 7 years for being taught in terrorism by al-Qaeda.
