Six fire engines and a turntable ladder were called to a major fire at an old brewery site in South Yorkshire.
Fire crews found a large amount of plastic was alight at the site of the former Oakwell Brewery on Pontefract Road, Barnsley.
The incident happened at about 11pm on Sunday night.
At the height of the blaze, six fire engines and a turntable ladder had been called to the scene.
Firefighters battled through the night for more than 10 hours as they attempted to bring the large blaze under control.
Crews finally left the scene at about 9am on Monday morning.
South Yorkshire Fire & Rescue Service has returned to the site to check for further hotspots, because the fire was so deep-seated.
Machinery is being used to move plastic to ensure it does not reignite.
A spokesman said an investigation will be carried out into the cause of the fire, once it is confirmed to be completely out.
