He said: "I saw a young lad running out from the workshop unit trying to find a fire extinguisher from a next door building.

"Soon after it sounded like fireworks were going off and flames and plumes of smoke started coming out of the unit.

"The flames took hold straight away.

"There is a shed company and shepherds hut company next door so there is a lot of wood nearby but thankfully nothing else caught alight."

The fire had been brought under control by 5pm and the fire service issued a stop message at 5.40pm.
