More than '400 people' went to a quarry last night during the heatwave 'without consideration of the risk', police have said.

Yesterday, Monday, July 18, officers were called to the Jamestone Quarry in Haslingden, where reports of more than 400 people attending the site gathered without consideration for the risks.

It comes as repeated warnings are being made about swimming in open water during the heatwave after numerous men and boys have drowned over the past 10 days after getting into difficulties in canals, lakes and quarries.

Officers handed out more than 25 fixed penalty notices to vehicles blocking, or obstructing traffic in Grane Road, Haslingden, and extra patrols will also be in place this afternoon from the neighbourhood teams over in Rossendale, alongside officers from TacOps to deal with any anti-social or criminal behaviour that occurs.

Lancashire Fire and Rescue Service will also be at Jamestone Quarry to divert people away from the area and give water safety messaging.  

Sgt Craig Leech said: “With the warmer weather brings a large number of people over to Haslingden, as they will have no doubt heard about the Jamestone Quarry we have here.

"However, as a result of that we see an increase in parking along Grane Road which not only is anti-social, but is a danger to other road users.

“The quarry is also privately owned land, which without expressed permission from the landowner is a trespassing risk.

“We know that people may not agree with us, but two teenagers have died in the North West in the last two weeks.

"So we can keep people safe, patrols will be increased in warmer weather between ourselves in neighbourhood and TacOps and we will be taking action to try and stop another death from happening – even if it’s an unpopular opinion – we ask residents and visitors to not take the risk.

"One dip in the water could cost you, or your child their life and it is not worth it.”

Head of Prevention for LFRS, Mark Hutton, added: “There are many hidden dangers of swimming in open water.

"The shock of cold water can get even strong swimmers into difficulty, it doesn’t matter how fit and healthy you are, the water is always stronger.

"The water can be deep, submerged objects may not be visible and it’s difficult to estimate the depth before you get in.

"Whilst swimmers may be able to enter the water, there are not always suitable places to climb out.

“Finally, we urge parents to have conversations with their teenage children about water safety. There are materials available on the Royal Life Saving Society’s website to help parents learn more about water safety.”

This comes after two young boys are in hospital after being rescued from the water at Blackpool pier yesterday evening.

Police said the 14-year-old boy is in a critical but stable condition at Alder Hey Children’s Hospital in Liverpool and the 12-year-old is at Blackpool Victoria Hospital where he is described as poorly, but not critical.

Earlier this month a boy drowned while swimming in a quarry near Wigan.
