Non-FBU firefighters have entered the building on Pier Street wearing breathing apparatus and are using a hose reel to tackle the fire, which is not believed to be serious.

The road is currently blocked and a cordon has been put in place.
UPDATE @ 23:30 – Southern Vectis buses are currently unable to serve Albert Street or the Boots bus stop and are advising passengers of Route 3 buses in either direction to make their way to the Central Car Park bus stop.
UPDATE @ 23:51 – Residents living above the food store have not been evacuated.
Reports suggest smoke was seen coming from the rear of the building, possibly relating to cooling units.
UPDATE @ 00:10 – Firefighters have now left the scene of the incident and the road has fully reopened.
A faulty chiller unit has been identified as the source of the smoke.
