Firefighters have spent six hours battling a blaze at a workshop in Nettlestead where the roof collapsed.

Around 15 crew members tackled the flames at the single-storey workshop in Gibbs Hill last night.

Three fire engines were called at 6.40pm and prevented the blaze from spreading to nearby buildings.

It was reduced to a single crew at 10.30pm and an hour later, crew began to damp down the area before declaring the scene safe at 12.30am.

There were no reports of any injuries and the cause is being investigated.
