Looters have broken into a bar which has been shut since the blaze which engulfed the nearby Glasgow School of Art.
Police received a report of a break-in at Campus on Sauchiehall Street around 3.20am on Thursday.
The bar is inside the cordon which was put up to seal off the area following the blaze at the art school which started at around 11.20pm on Friday June 15 and spread to nearby buildings including the O2 ABC.
Experts have urged the public to stay away from the gutted Mackintosh building at Glasgow School of Art over fears parts of it could collapse “without warning”.
Police are investigating the break-in at the bar.
A police spokesman said: “Inquiries are continuing following a break-in at premises on Sauchiehall Street, Glasgow at around 3.20am on Thursday June 21.”
The city council said other reports have been made of people breaching the cordon, raising safety concerns, and urged people to stay away.
Glasgow City Council’s head of building control Raymond Barlow said: “I fully understand people’s desire to get back into their property and if we could safely do anything to facilitate that then we would.
“However surveys in recent days have shown us that the West and East elevations remain of significant concern.
“This means that there is a risk that parts of the building might fall into Scott Street or Dalhousie Street. This could happen without warning.”
At the height of the incident, more than 120 firefighters were involved in fighting the blaze.
There have been no reports of any casualties, although emergency services had to evacuate some properties in the area.
