Firefighters say that the building that was alight in Dundee city centre this afternoon is structurally unsafe.
Four fire engines, police and an ambulance were called to the scene.
A Scottish Fire and Rescue Service (SFRS) spokeswoman said: “We got a message at 15:02 to say the fire has been extinguished.
“The structural engineer has advised that the building is unsafe.
“From a safe area, we are removing any remaining hot spots.
