Shortly before midday on Saturday, 20 March 1993, The Samaritans in Liverpool received a bomb warning by telephone. According to police, the caller said only that a bomb had been planted outside a Boots shop. Merseyside Police sent officers to branches of Boots in Liverpool and warned the Cheshire Constabulary, who patrolled nearby Warrington. About 30 minutes later, at about 12:25, two bombs exploded on Bridge Street in Warrington, about 100 yards (90 m) apart. The blasts happened within a minute of each other. One exploded outside Boots and McDonald's, and one outside the Argos catalogue store. The area was crowded with shoppers. Witnesses said that shoppers fled from the first explosion into the path of the second. It was later found that the bombs had been placed inside cast-iron litter bins, causing large amounts of shrapnel. Buses were organised to ferry people away from the scene and 20 paramedics and crews from 17 ambulances were sent to deal with the aftermath. Three-year-old Johnathan Ball died at the scene. He had been in town with his babysitter, shopping for a Mother's Day card. The second victim, 12-year-old Tim Parry, was gravely wounded. He died on 25 March 1993 when his life support machine was switched off, after tests had found only minimal brain activity. Another 54 people were injured, four of them seriously. One of the survivors, 32-year-old Bronwen Vickers, the mother of two young daughters, had to have a leg amputated, and died just over a year later from cancer. The Provisional IRA issued a statement the day after the bombing, acknowledging its involvement but saying: Responsibility for the tragic and deeply regrettable death and injuries caused in Warrington yesterday lies squarely at the door of those in the British authorities who deliberately failed to act on precise and adequate warnings A day later, an IRA spokesman said that "two precise warnings" had been given "in adequate time", one to the Samaritans and one to Merseyside Police
