Eyewitness Paul Barnfield told BBC Radio Sheffield he had been driving to work along Sheffield Road when he had seen part of a building "exploding out into the road".

"It blew all the side of the building out," he said. "Black debris was just spread across the road. Another 10 seconds and I'd have been in it."

Part of Sheffield Road was closed for nearly three hours.

Police said the explosion had also caused damage to cars parked across the road from the site.
