An investigation into the cause of a huge blaze at a recycling plant in Sheffield is continuing this morning.
The fire at Richard Fletchers on Clement Street, Darnall, broke out on Thursday night and crews battled into the next morning to extinguish all the flames.
Fire investigators retrieved CCTV footage from the site in the hope of establishing what started the blaze.
There were five fire engines and 25 firefighters at the recycling plant at the height of the blaze.
When crews arrived they were met with mountains of burning waste.
Diggers had to be used to break down the mounds so that firefighters could get to the flames underneath.
