Investigators have been unable to determine what started the fire that swept through Glasgow School of Art's Mackintosh building, causing "catastrophic damage" more than three years ago.
The Scottish Fire and Rescue Service (SFRS) said that due to the extensive damage at the site and the fact physical evidence was destroyed in the fire it has been unable to establish how the blaze started and recorded the origin and cause as "undetermined".
Fire broke out at the world-renowned building, designed by Charles Rennie Mackintosh, late on June 15, 2018 as it neared the end of a £35 million restoration project following a previous fire in May 2014.
