"On 22 July 2005, the Metropolitan Police were searching for four suspects in four attempted bombings carried out the previous day; three at London Underground stations and one on a bus in Haggerston. As the perpetrators had not died in the failed suicide bombings, a large police investigation and manhunt began immediately. An address in Scotia Road, Tulse Hill, was written on a gym membership card that was found inside one of the undetonated bags used by the bombers."
