It is understood the pane shattered near the front entrance of the building on Thursday morning, but nobody is believed to have been injured.

The £842 million hospital opened in April 2015.

An NHS Greater Glasgow and Clyde spokesman said: “An external decorative panel this morning fell from the 10th floor of the Queen Elizabeth University Hospital building.

“Fortunately no-one was hurt and the area was immediately secured.

“Facilities staff are on site to assess and repair the damage. It is not at this time clear why this happened.”
