A Whitemoor prisoner today (16) pleaded guilty to attempted murder of a fellow inmate when he appeared at Peterboorugh Crown Court via a video link.
Kevin McCarthy, 49, is due to be sentenced at Peterborough Crown Court tomorrow (Wednesday 17).
The incident happened at the prison on October 2, 2016.
The victim was taken to hospital where he was treated for life threatening injuries to his neck.
Armed robber McCarthy, a native of Glasgow but formerly resident in Kent, admitted that he attacked Damien Fowkes, 41, also of HMP Whitemoor.
In 2011 Fowkes, already serving a life sentence for armed robbery, was jailed for a minimum of 20 years for the attempted murder of Soham murderer Ian Huntley.
Fowkes had attacked Huntley with a weapon he made by melting a razor blade onto plastic cutlery, leaving the killer with a seven-inch gaping hole in his neck.
