A fire, which broke out at a Lancashire plastics recycling site, is being treated as suspicious by police and fire fighters.
Eight fire engines were called to a facility owned by Stephen Barnes at Padiham near to Burnley. The plastics storage site was previously owned by Lancashire County Council until 18 months ago.
Lancashire Constabulary are treating the blaze as suspicious after an investigation by Lancashire Fire and Rescue Service found the fire was started when a bale of plastic was set alight.
Police are studying CCTV footage which seems to show a number of youths in the area at the time.
DC Martin Legdon of Burnley CID said: “This was a reckless and extremely dangerous thing to do and it is fortunate that the fire was spotted and fire officers were able to extinguish it before it spread any further.”
