A 41-year-old man has been arrested in connection with a fire which burned for more than two weeks at a farm in Nottinghamshire.
The blaze broke out at Oakfield Farm, in Forest Lane, Walesby, on September 21 last year.
The man was arrested at an address in Sneinton today (November 8) after a joint operation between Nottinghamshire Police and the Environment Agency.
On entry to the property, officers found 40 suspected cannabis plants. The man is also being questioned in connection to this discovery.
According to the Environment Agency, the blaze contained dumped illegal waste.
There was no permit allowing waste to be stored at the farm.
The Environment Agency said the man will also be questioned about the discovery of illegal waste at two sites in Leicestershire.
Peter Haslock, area enforcement team leader for the East Midlands, said: "The arrest was made as part of a joint investigation involving enforcement officers from the Environment Agency and colleagues from Nottinghamshire Police.
"We know the Walesby site did not have a permit for waste activity and we believe the waste was involved in the fire.
"These are extremely serious cases and the Environment Agency is determined to bring the culprits to justice.
"We are working closely with partners to share intelligence on illegal wast activity - and we’re encouraging property and land owners to be vigilant."
