Safety netting has been erected around the Queen Elizabeth University Hospital (QEUH) in Glasgow, Scotland, after a glass panel fell from the 10th floor, according to an article on the BBC website.
An investigation into the incident earlier this month proved inconclusive, according to NHS officials.
Panels have fallen from the building at least three times since it opened.
In the latest incident the panel shattered near the front entrance but no-one was injured. But the shattered pieces recovered were not large enough to analyze and determine the cause.
The QEUH opened in April 2015 and was featured in the BBC series Scotland's Superhospital.
