Firefighters were today investigating the cause of a blaze which sent huge black plumes of thick smoke rising high above Sheffield last night.
South Yorkshire Fire and Rescue Service said they received ‘very many’ calls from the public alerting them to the blaze on Douglas Road near Neepsend.
Fire broke out at a fibreglass factory called Antiquity Group just before 6.30pm, the brigade said.
By 7pm bystanders had gathered on the surrounding streets to watch as eight fire engines, plus police cars and vans, raced to the scene.
A pall of smoke could be seen for miles, and the sound of crackling flames and bangs could be heard.
Forty firefighters from Central, Darnall, Mansfield Road, Low Edges, Aston Park, Rotherham and Barnsley stations all doused the flames.
The fire was out by 8.30pm, but crews remained at the scene throughout the night damping down.
A brigade spokesman said no casualties or hazardous materials had been reported. An investigation into the cause was due to begin today.
