Medical staff are believed to have entered the retail outlet on Edinburgh’s busy shopping thoroughfare as Storm Ali continues to wreak havoc across the Capital.
The extent of any injuries is not yet known.
A witness at the scene confirmed to the Evening News that at least one section of masonry had come loose and fallen as wind gusts of up to 90mph batter Edinburgh.
Police have cordoned off the section of Princes Street outside of Topshop.
Trams have been stopped from travelling past the store near South St Andrews Street. They are now terminating at the West End.
Officers were called at 12:30pm and have cordoned off the road and pavement in the vicinity.
It is understood a piece of lead is loose on the roof and the precaution has been taken due to the high winds being experienced in the Capital.
The outlet is situated on Princes Street adjacent to the Waverley Mall and one of the main entrances to Edinburgh Waverley station.
