Young Cheshire Police constable Mark Toker was not best pleased about being asked to work overtime at the end of a long shift on February 25, 1993.
Police staffing numbers in Warrington, where the 25-year-old was on duty, were reduced that night due to several local officers attending a function. Reluctantly, the married dad-of-one agreed to stay on after his shift ended at 10pm.
That twist of fate would write his name into the history of one of the most astonishing terrorist incidents to hit north west England.
