A thug who murdered a dad-of-two over a kebab has been convicted of assaulting a prison officer at HMP Shotts while serving his life sentence.
Dean Logan, 27, was just 15 years old when, along with two other teenagers, he carried out an unprovoked drug and drink fuelled attack on Nachatter Singh Bola.
In January 2011 he was ordered to serve a minimum of nine years for his part in the murder.
