Two prisoners given whole-life sentences for the murder of a fellow inmate were "calm and unemotional" as they killed him, a judge has said.
Lee Newell, 44, from Norwich, and Gary Smith, 48, were convicted of murdering child-killer Subhan Anwar in his cell at HMP Long Lartin in Worcestershire.
They had tied him up and strangled him after convincing Anwar he was being taken hostage so he would not resist.
Both defendants refused to leave the cells at Warwick Crown Court to attend the sentencing this morning.
Mr Justice Jeremy Baker, who addressed his remarks to Smith and Newell, from Leicester, despite their absence, said: "You both acted in a calm and unemotional manner ... eventually leaving [Anwar's] cell with items of his personal property being worn as trophies of your exploits."
