A body was found in a Lincolnshire reservoir.
Police were called to Covenham Reservoir on Saturday morning, July 4, after the body of an elderly woman was found.
According to a passerby, the body was seen floating in the water, reports Grimsby Live.
Uniformed Lincolnshire police officers have been spotted in the tank, while detectives are investigating the incident.
The reservoir, which is operated by Anglian Water north of Louth, supplies water to the northeastern areas of Lincolnshire and is popular with hikers who live nearby.
The discovery came days after police warned people not to dive in the water after groups of young people diving in the past few weeks have been reported.
The police urged people not to enter because cold water could cause shock to swimmers and there are hidden dangers such as toxic algae and currents.
Anglian Water, who runs the site, said earlier: “Following recent reports of transgressors accessing the Covenham reservoir and jumping from the control tower into the water, we would like to remind people not to enter the water under any circumstances.
“Swimming in our tanks is illegal and extremely dangerous.
“The water may seem inviting on a hot day but there are hidden dangers, currents and cold temperatures below the surface
“Covenham is a fully operational site and our staff are not trained as lifeguards if visitors face any difficulties.
“Please stay safe and help us spread the word by sharing this message.”
