Bradford-born serial killer Donald Neilson killed four people in 1970s.
Bradford-born serial killer Donald Neilson, who was known as the 'Black Panther', has died in hospital.
Neilson was given four life sentences in 1975 and was one of a small group of prisoners who were told they would spend the rest of their lives behind bars.
He was convicted of four murders, including that of 17-year-old heiress Lesley Whittle in 1975, as well as three sub-postmasters during armed robberies.
In 2008 he lost an appeal against his sentence.
The 75-year-old was taken to hospital from Norwich prison with breathing difficulties on Saturday and was pronounced dead yesterday evening.
