Christopher Alder was a trainee computer programmer and former British Army paratrooper who had served in the Falklands War and was commended for his service with the Army in Northern Ireland. He died in police custody at Queen's Gardens Police Station, Kingston upon Hull, in April 1998. The case became a cause célèbre for civil rights campaigners in the United Kingdom. He had earlier been the victim of an assault outside a nightclub and was taken to Hull Royal Infirmary where, possibly as a result of his head injury, staff said his behaviour was "extremely troublesome." He was escorted from the hospital by two police officers who arrested him to prevent a breach of the peace.
