Fire at Oughtibridge refrigeration business 'was arson'
A fire at a refrigeration plant which spread to 10 vehicles and caused explosions is believed to have been started deliberately.
Fire crews were called to the blaze at Samples Express on Oughtibridge Lane, north of Sheffield, at 03:30 GMT following loud explosions.
The fire service said they were caused by gas exploding in three refrigerated lorries, which had been set on fire.
The blaze then spread to another seven vehicles and a building nearby.
Water used to extinguish the fire immediately froze as it hit the road, the fire service said, and police had to shut the road between the Cross House Road and Oughtibridge Lane junctions on Skew Hill Lane.
The fire was extinguished by 07:00 GMT.
South Yorkshire Police are now investigating the cause.
