Police are asking people who live in rural area of Northamptonshire to be vigilant towards the possibility of illegal raves this weekend.
A police spokesman said: “Officers are determined to maintain their robust approach to raves and are encouraging support from rural communities to be our eyes and ears, for the best chance of preventing an event before it starts.
“We would encourage you to report any suspicious circumstances, such as cars acting suspiciously, driving around slowly looking at fields, outbuildings and barns, and any potential marking of locations, such as paint marks on the road surface or ribbons on gates and in hedges.
“Information from the public is invaluable; if you suspect a rave to be starting, maybe by the appearance of a number of vehicles at a location, please call 999 immediately.
“Any information or concerns about potential raves, please report using the non emergency 101 number or anonymously via Crimestoppers on 0800 555 111.”
