A warning has been issued to anyone thinking about swimming in open water during the summer. Police have received numerous calls and complaints about people swimming in the lakes in Hoveringham and the riverfront at Gunthorpe.
The Nottinghamshire force says open water swimming can have deadly consequences. They have warned"the water may look calm on the surface, but there may still be strong undercurrents that could pull even a strong swimmer under".
Police say they have also received complaints about people jumping off the bridge and into the River Trent. Despite the warm weather temperatures just below the surface can often be freezing cold - and could quickly lead to severe cramp and hypothermia.
