A young offender serving life for "internally decapitating" a 61-year-old man was handed more jail time for punching three warders during a football field bust-up at a junior prison.
Tristan Kiely was inside for brutally murdering Frank Sinclair by repeatedly stamping on his head in East Kilbride in January 2019.
Now 20, he was only nine months into his life sentence - for which he'd been told he would serve at least 11 years in custody - when he flailed at the warders at Polmont Young Offenders' Institution, Stirlingshire.
