TEENAGERS have been warned against swimming in open water following reports of anti-social behaviour.

Cheshire Police have received numerous reports of youths who have been gathering in several swimming spots around Northwich, particularly at Nunsmere Lake in Oakmere.

Insp Dave Snasdell, from Northwich Local Policing Unit, also said there has been several reports of anti-social behaviour around Marbury, Hunts Lock in Northwich, Pickmere Lake and Whitley Quarry.

Police fear teenagers have been swimming while under the influence of alcohol, and has warned that swimming in open water could have fatal consequences.

Insp Snasdell said: “Police have received reports from members of the public of youngsters congregating at similar locations, swimming, drinking alcohol and acting in an anti-social manner including littering and lighting fires.

“We have had numerous calls relating to anti-social behaviour at several locations.

“While we are looking into this issue, we want to take the opportunity to remind people that although it may seem like harmless fun, swimming in open water without supervision of an adult could have tragic consequences.

“Swimming in lakes and rivers is very dangerous with many unseen hazards and the cold deep water fatigues people very quickly and even strong swimmers can find themselves in difficulty.

“The use of alcohol is evident at these locations and swimming after consuming alcohol increases the risk of harm.”

Insp Snasdell said parents have been seen dropping their children off at locations and urged them not to encourage children to congregate and swim at these locations, where they could be at risk.

Anyone with any information should report it to police on 101 or via Crimestoppers, anonymously, on 0800 555 111.
