A child sex killer who sexually assaulted and strangled a seven-year-old boy has been found dead in prison, it emerged today.
A fellow prisoner was arrested on suspicion of murder following the death of Colin Hatch
, 38, who was jailed for life in 1994 for the murder of Sean Williams while on parole for another sex attack.
Seven-year-old Sean died at the hands of Hatch after he was abducted and sexually assaulted. Hatch smirked when he was found guilty of the child's murder
A spokesman for Humberside Police said: 'Officers Police are currently investigating a prisoner death at Full Sutton Prison last night.
'A 38-year-old male prisoner died in the incident. A 35-year-old male prisoner has been arrested on suspicion of murder. Give that guy a fucking medal.
He was found guilty of murder and when jailing Hatch, who had a string of convictions for assaulting young boys, Judge Nina Lowry said he was 'highly dangerous' and told him it was not possible to envisage a time when he could be released safely.
Unemployed Hatch, then 21, was convicted after the jury of six women and six men deliberated for less than three hours and smirked when he heard their verdict.
Just over two years earlier, he was jailed for three years for assaulting a boy of eight in almost identical circumstances.
His lawyer warned he could kill when he was released.
Within 11 weeks of being paroled in April 1993, Hatch fulfilled that chilling prediction.
Sean was abducted, sexually assaulted and then choked to death after Hatch lured him to his tower block home in Norfolk Close, Finchley, north London.
A postman discovered the youngster's body taped up in bin liners and dumped in a lift.
A year before he was jailed for attacking the eight-year-old, Hatch abused a boy of 10, dragging him into the same lift where he was later to dump Sean's body. He indecently assaulted the youngster.
Hatch had a string of previous convictions from the age of 15 for attacks on six young boys.
At his previous trial for indecently assaulting the eight year-old boy and choking him until he lost consciousness, psychiatrist Dr Anthony Wilkins recommended that Hatch was a 'menace to the public' and should be sent to Broadmoor top security hospital.
But Broadmoor had not considered Hatch dangerous enough at the time, Dr Wilkins said. Instead he was jailed for three years, as the judge was given no alternative.
