A former soldier who shot dead four members of his family before walking into a police station with a bag of weapons and a homemade bomb was detained on Wednesday for a minimum of 15 years, police said.

David Bradley, 41, will serve his sentence in a secure hospital after admitting manslaughter on the grounds of diminished responsibility at Newcastle Crown Court.

He shot his uncle, aunt and two cousins through the head at their three-bed semi-detached home in Newcastle, England, in July 2006.
