The body of a 39-year-old man has been found in the area of Delapre Lake in Northampton.
The man’s body was found by a member of the public on Friday morning and police and paramedics were called to the scene.
Volunteers working at Delapre Abbey were asked at about 8am today to open gates at Delapre Park to let police vehicles through to woods behind the abbey.
It is understood officers were making their way to the water’s edge on the abbey side of the lake.
Police officers have since been stationed on footpaths to prevent pedestrian access to the scene. An eye-witness reported that fishing equipment had been taken away by police officers.
However, it is understood that police believe the man may have been a dog walker who had been in the water, then died after getting himself ashore.
A police spokeswoman said: “Police were called to Ransome Road lake, near Cotton End, in Northampton, shortly before 8am this morning, after the body of a 39-year-old man was discovered by a member of the public.
“Officers attended the scene with colleagues from the East Midlands Ambulance Service.
“The man’s death is not being treated as suspicious and a report will be prepared for the coroner.”
