More than 2,000 bags of waste associated with cannabis production has been dumped in a North Yorkshire town so far this year.
The council and North Yorkshire Police are working together to try a find those responsible after a series of large scale flytips.
Most recently, 61 bags worth of cannabis plant remnants and equipment used to grow the illegal plant were found dumped near Hutton Rudby. It brings the total number of bin bags collected so far this year up to 2024 bags. They had been left in hedgerows across the district.
Police say, given the amount of waste, it must have been transported in a van or pick up before being flytipped.
