A depraved torturer has been given extra jail time after being caught with a mobile phone.
Colin Coats is currently serving a life sentence for the kidnap and murder of Glasgow woman Lynda Spence in 2011.
The 50-year-old was jailed for a minimum of 33 years for the killing but has now been handed an additional 12 months on top of his sentence.
Coats was found with the phone at HMP Glenochil, reports the Daily Record.
The killer appeared at Alloa Sherrif Court last month where he pled guilty to being in possession of the banned handset.
A source said: "He was gutted when the phone was discovered. Coats was found with the phone at HMP Glenochil.
"Coats still has a lot of pals who he keeps in touch with and the phone was a lifeline.
"He'd got into the habit of wiping the phone's memory after every call and message in case he got caught.
"He had the phone for a while before it was found. Having 12 months added to his sentence doesn't bother him."
Sadistic Coats bundled Lynda off a Glasgow street and held her hostage at a flat in West Kilbride, Ayrshire.
He battered her, hacked off parts of her body and burned her with an iron for a fortnight over a financial dispute.
Coats has refused to reveal how and where he disposed of her body, leaving her grieving parents unable to lay her to rest.
He was moved to HMP Glenochil in 2019 after being caught with a pointed plastic weapon, measuring three inches long, stashed down his trousers at HMP Shotts, in Lanarkshire.
The blade was found after trouble flared between cons and he was sentenced to four months to run alongside his life sentence.
Coats denied he had murdered Lynda, 27, claiming she was alive and well, but was convicted following an 11-week trial in 2013.
The High Court in Glasgow Coats and pal Philip Wade abducted the "financial adviser" on April 14, 2011.
The trial heard that Lynda had "ripped people off" with Coats believing she cheated him out of £85,000 in a dodgy land deal.
Despite having refused to reveal what happened to Lynda's body, he was allowed compassionate leave from prison to attend the funeral of his mum, Catherine, 80, in November 2016.
