A "deliberate ignition" caused a major building fire in north Wales, the fire service has confirmed. Crews were called to the former retail showroom on Station Road in Bangor shortly before 8.55pm on Monday.
Police urged people to stay away. Three fire engines, two from Bangor and one from Menai Bridge and an aerial ladder platform also from Bangor fought the blaze, as flames and smoke consumed the building.
North Wales Police said: "Due to an ongoing fire on Holyhead Road in Bangor the road is closed from the Bangor Train Station to Morrisons. "Please avoid the area if possible. The road will be closed for quite a while."
