Belfast. Sinn Féin had been elected to take part but were barred because the IRA had not resumed its ceasefire or agreed to disarm. Details of the bombing The IRA's South Armagh Brigade was tasked with planning and carrying out the attack. It had also been responsible for the Canary Wharf bombing in February, and the Bishopsgate bombing in 1993. Its members mixed the explosives in Ireland and shipped them by freight from Dublin to England. In London, the bomb was assembled and loaded into the back of a red and white Ford Cargo van. On 14 June it was driven north towards Manchester, accompanied by a burgundy Ford Granada which served as a "scout car". Discovery At about 9:20 am on Saturday 15 June 1996, the Ford van was parked on Corporation Street, outside the Marks & Spencer store, near the Arndale Centre. After setting the bomb's timer, two men—wearing hooded jackets, baseball caps and sunglasses—left the vehicle and walked to Cathedral Street, where a third man picked them up in the Ford Granada, which was later abandoned in Preston. The truck had been parked on double yellow lines with its hazard lights flashing. Within three minutes a traffic warden had issued the vehicle with a parking ticket and called for its removal. At about 9:40 am, Granada Studios on Quay Street received a telephone call claiming that there was a bomb at the corner of Corporation Street and Cannon Street and that it would explode in one hour. The caller had an Irish accent and gave an IRA codeword so that police would know the threat was genuine. Four other telephoned warnings were sent to television/radio stations, newspapers and a hospital. The first policeman to arrive on the scene noticed wires running from the van's dashboard through a hole into the back and reported that he had found the bomb. Forensic experts later estimated that the bomb weighed 1,500–1,600 kg (3,300–3,500 lb) and was a mixture of semtex, a military-grade plastic explosive, and ammonium nitrate fertiliser, a cheap and easily obtainable explosive used extensively by the IRA. Components of what may have been a tremble trigger were also found later, designed to detonate the bomb if it was tampered with. Evacuation At 10:00 am, there were an estimated 75,000–80,000 people shopping and working in the vicinity. An evacuation of the area was undertaken by police officers from Bootle
