Fife Police have made a renewed appeal for information following the fire at Tullis Russell in December.
DS Stewart Andrew who is leading the investigation said: “Extensive reviews of CCTV cameras has revealed a man and a woman at Glenrothes bus station around that time and I am keen to speak to them both.
“We believe we have the individual responsible in and around the bus station area, shortly before the fire. I am keen to trace a lone female who was caught on CCTV walking from the area of the Golden Acorn, through the bus station at or around 2am on the morning of Tuesday, 27 December 2011.”
