Read the latest magazine Industry News Roofer Fails in Attempted Murder Conviction Appeal 13 December 2018 A ROOFER found guilty of attempting to kill a colleague following a drinking session just days after they first met at work, has had an appeal against his conviction rejected, despite claiming he was acting in self-defence. Thomas Telford, who was sentenced to nine-and-a-half years’ in prison after being convicted of the attempted murder of Callum Thomas, argued that the trial judge was wrong to rule that his claim of self-defence could not apply to the case. Attempted Murder Conviction Telford was found guilty in November 2017 following a trial at Livingston Crown Court. Charges against him included attempted murder, assault of a neighbour and disposal of a weapon. The trial heard evidence that Telford and the complainer Thomas, who were both roofers, had first met in August 2016, when working on a site in Edinburgh city centre. After finishing work on 12 August they went drinking, before going back to Thomas’ house. Thomas told the court that he had gone for a shower and that when he returned Telford was stabbing the wall with a kitchen knife. Thomas punched Telford, and Telford retaliated by stabbing him twice. A neighbour, who heard the commotion, ran into the flat and tried to intervene, only to be pinned against a wall by Telford. Thomas reportedly tried to dive over a couch to escape to the kitchen area, but as he did so he was stabbed a further four times in the back. Failed Appeal Telford lodged a special defence of self-defence in respect of his attempted murder charge, but he did not give evidence. The trial judge concluded that the claim of self-defence failed as a matter of law, as there was no imminent danger to Telford and he had a means of escape when he had used the knife. Refusing the appeal, the appeal judges said they were “unable to fault” the trial judge’s decision. >> Read about more roofing court cases in the news Previous article Lords to Debate Report on Off Site Manufacture for ConstructionNext article Mock Trial Helps Construction Team Master Health and Safety Challenges Share article You may also like View all News Industry News +2 20 March 2026 RA Issues Revised Safety Guidance on Rooflight Covers Awards and Events +3 20 March 2026 The Great British Slate Off Returns for 2026 Green Roofs +3 20 March 2026 Swansea Joins Global Network of Biophilic Cities Featured Solutions +3 19 March 2026 Flush Fitting Rooflights by Clement Sign Up to Roofing Today Stay up to date with all of the latest news from Roofing Today by signing up to our weekly Bulletins… Sign Up Today Get in Touch Check out the latest issue 123 March-April 2026 View Now Past Issues Get in Touch
