Parties in Lancashire woodland patrolled by police
Police have begun patrolling woods in north Lancashire after fears were raised over young people holding all-night parties there.
Groups of up to 60 teenagers have been meeting at rural areas in Silverdale, Bolton-le-Sands and Warton to camp out and drink alcohol, police said.
The force said it had received complaints of criminal damage, theft and abandoned rubbish at the sites.
It fears the gatherings will impact on local residents and endanger wildlife.
Officers said some of the woods are home to deer who could injure themselves on broken glass left at the sites.
Pc Linda Head, community beat manager for Bolton-le-Sands, said: "What they are doing is advertising on social networking sites about these parties, and from there we are getting groups of approximately 60 young people heading up to these rural areas and having camp-outs overnight.
"A lot of the time they are drinking alcohol and lots and lots of rubbish is being left over.
"Some of these areas are sites of special scientific interest, they are there for everybody to enjoy."
She added: "I think it is up to parents to try and ensure the safety of these young people."
Pc Head said the parents of some of the young people, who are thought to be aged between 15 and 23 years old, have been seen dropping them off at these sites with camping equipment.
"Parents need to be aware of their responsibilities - they should know where their children are and what they are doing," she said.
