Inmate arrest over 'murder' of child killer

A prisoner has been arrested on suspicion of murdering child sex killer Colin Hatch at one of Britain's most secure jails.

The 38-year-old killer died following an incident at the maximum-security Full Sutton prison near York on Tuesday. He was jailed for life in 1994 after being convicted of killing seven-year-old Sean Williams at his home in Finchley, north London, while on parole for a previous child sex attack.

A 35-year-old prisoner has been arrested on suspicion of murder.

He is in custody at the East Yorkshire prison and will be moved to a police station at a later date, Humberside Police said.

Hatch had a string of convictions for assaulting young boys when he was jailed for the murder of Sean Williams. Jailing him, 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.
