Derbyshire police have renewed warnings about entering open water to swim or cool down during the hot weather after a teenager died after getting into difficulty.

Officers made the appeal after the body of an 18-year-old man was recovered from the River Derwent at Darley Abbey Mills, on Friday.

Derbyshire police said:” Entering open water like the River Derwent, or other locations such as old quarries, might seem like a quick break from the heat but it is extremely dangerous.

“Hidden currents, sudden changes in depth, underwater hazards and cold-water temperatures can cause even the strongest swimmers to get into difficulty within seconds.

People have been urged to avoid swimming in open water.

“If someone is in trouble in the water, call 999. Do not enter the water with them.

“If you are in trouble in the water float to live – lie back, use your arms and legs to float, and call for help when you are able.

“This applies to everyone, including swimmers and all watercraft such as boats, canoes, paddle boards and kayaks. If you have children, please make sure they are aware of the dangers and remind them never to enter the water.

“We are issuing this reminder following the death of an 18-year-old man, whose body was recovered from the River Derwent at Darley Abbey Mills, Derby, after he got into difficulty.

“Please share this advice as widely as you can, to help ensure people enjoy the summer weather safely and responsibly.”
