Farmers have been warned to be on their guard against harvest time arson attacks.
The country land owners’ group CLA East says straw stacks are typically targeted in July and October costing farmers thousands of pounds.
CLA eastern surveyor Claire Wright said: “Deliberate straw stack fires destroy important material used in arable and livestock farming – it’s not just a by-product. They can spread rapidly, threatening buildings, livestock, machinery and, potentially, human lives.”
Suffolk Police’s Rural and Wildlife Crime Officer PC Mark Bryant said: “Stacks often have to be located next to tracks or roadways to allow lorries to have access, but this also allows access to people who wish to set fire to them.
“We advise that wherever possible there should be fewer more isolated stacks with generally increased security – this could include restricting access to farm tracks.”
