This is why shoppers were evacuated from Sheffield ASDA store
Pictures and video emerged online of customers and staff being led out of the shop in Chaucer Road, Parson Cross.
Firefighters from Rivelin Fire Station were called to the scene at just after 8pm but they discovered there was no blaze.
A fire brigade spokesperson said a fault with the sprinkler system had triggered the alarm which meant people inside had to be evacuated from the building.
