Lincolnshire Police is warning farmers and landowners about requests to store rubber, bales and wood chippings on their land.
The danger of such waste catching fire, and the sharp-smelling fumes that would be given off, is on top of the cost to farmers for having it removed which could run into several hundred thousand pounds.
A Lincolnshire Police spokesman confirmed that one farmer from the county was left with a bill of £40,000 to clear this type of waste, while another has to pay out £250,000 or run the risk of a possible arson attack.
The spokesman said: “There is a huge cost for the victims of these scams and we urge people to remain vigilant because of this.”
