A fire involving 3,000 tonnes of baled plastic waste was likely started by deliberately, Lancashire Fire and Rescue has said.
The fire broke out at Fleetwood recycling centre, which is operated by Lancashire County Council, on Saturday evening.
Around 50 firefighters were involved in tackling the blaze at its height. According to a tweet by the fire department, it was decided that a “controlled burn” was the cleanest option of subduing the fire.
Local roads were closed and residents at a nearby caravan park were told to stay indoors. No-one was hurt.
John Taylor of Lancashire Fire and Rescue said because of the remote location and “a process of elimination” the fire was being treated as arson.
Lancashire Constabulary yesterday (17 April) released a teenage boy on police bail in relation to the fire.
The 16-year-old was questioned but later released pending further enquiries.
“Enquiries are underway to ascertain the cause of the fire. It is not yet known whether it was started deliberately,” it said.
