A thug once dubbed the most dangerous teenager in Scotland has been handed an extra 16 months in jail for stabbing two prison officers in a row over his dinner.
Darren Cornelius, 33, lashed out at prison guards as his evening meal was being served at his cell in HMP Shotts, Lanarkshire.
He flew into a rage over the delivery of the food and produced a 'small white' blade from his pocket.
