An investigation has been launched by police and fire officers after three fires started in the same place sent smoke billowing across the M65 motorway.
Two crews from Burnley Fire Station were called to the incidents on the Chestnut Business Park in Smallshaw Lane, Rosegrove, at 2-30am today.
Firefighters said a large amount of crumb rubber, used to manufacture children’s play areas, was well alight when they arrived.
They also discovered a further two fires on the site, one of which was dangerously close to a large number of flammable gas cylinders.
Crews dealt with the fire near to the gas cylinders and then battled for almost two hours to put out the rest of the flames.
Watch manager Steve Harrison said: “The smoke from this fire was drifting across the M65 motorway, and was called in from there.
“This fire is being investigated as a suspicious fire and inquiries will be continuing by the police and fire service.
“Deliberate fires can cost lives. They also put a strain on fire service resources that may be required elsewhere.
“Business owners are asked to ensure that the storage of flammable waste is kept away from gas cylinders or buildings.”
