A prisoner serving more than five years for a slash attack was found with a blade between his buttocks in HMP Perth. John McCormack, 35, was found with a sharpened piece of plastic while being moved into segregation in October 2019. Dundee Sheriff Court heard how McCormack’s life had been threatened by fellow inmates. Fiscal depute Stewart Duncan said: “It was revealed to be a piece of plastic, sharpened to the handle, covered in tape.” McCormack, a prisoner of HMP Addiewell, admitted possessing the weapon on October 15 2019. Sheriff Lorna Drummond deferred sentence until July and released him on bail to an address in Glasgow.
