An operation has been launched to tackle arsonists who set fire to straw stacks.
With harvest just around the corner, Cambridgeshire Police and Cambridgeshire Fire and Rescue are working together to investigate suspected incidents.
Operation Armitage recognises the impact straw stack fires have on farmers and is being run in conjunction with Countryside Watch and the National Farmers Union.
Insp Dick Turner, from the police’s Rural Crime Team, said: “Straw stacks appearing at the end of harvest are the result of 12 months of hard work by farmers and are a valuable commodity.
“We are working very hard with our partners to prevent the serious offence of deliberate straw stack ignition, through education and enforcement.
“There will be operations by officers throughout the season and we will be using CCTV and other covert tactics to ensure we reduce the opportunity for offending, and put before the courts those caught offending.”
Report suspicious activity to police on 101, or 999.
