The murder of Harry Collinson, the planning officer for Derwentside District Council, took place in 1991 at Butsfield, County Durham, England. At the time of the murder, the Derwentside District Council was involved in a dispute with Albert Dryden over the erection of a dwelling by Dryden in the countryside without planning permission. At approximately 9:00 am on 20 June 1991, as television news crews filmed, Dryden aimed a handgun—a .455 Webley Mk VI revolver—at Collinson and shot him dead. As the journalists and council staff fled, Dryden opened fire again, wounding television reporter Tony Belmont and Police Constable Stephen Campbell.
