Criminal: Simon Willerton's suicide in 1990 brought to six the number of young prisoners who hanged themselves in British prisons in just over six months, prompting public debate over conditions in remand prisons like Armley where overcrowding was so severe that no new inmates could be admitted. Simon faced a burglary charge over the theft of a hot-water bottle from an unoccupied flat. Less a hardened criminal than an immature, gawky teenager who never fitted in, Simon and his tragic death inspired this teleplay.
