Police had to move 60 teens from camping in private woodland near Runshaw College after residents complained.
People living in the estates around Worden Park are worried about groups of teenagers using nearby Atherton Clough Wood as a base camp, and have raised their concerns at the area’s PACT (Police and Community Together) meetings.
Coun Phil Hamman, who represents the residents of Leyland St Mary’s, said: “The woods have been used by teens for years as a place to go, but unfortunately nowadays, with things like cheap alcohol being sold in supermarkets, it changes the nature of how these youths spend their time.
“Worden Park itself has always had a problem with youngsters in the evenings too, but you can’t seal it off because there are usually activities being held there as well.
“There are also entrances around the back, near Parkgate Drive, so it would be impossible to stop people from going on the park.”
He added: “This type of thing happens in most places, so I don’t think Leyland is very different, but the problem seems to increase when we have nice weather.
“It’s a shame, but it’s a sign of the times I’m afraid.”
South Ribble MP Lorraine Fullbrook added: “It is causing people a lot of angst.
“The issue seems to be from youths living in the area who go to Tesco for alcohol, and then take it to the park or nearby woods.
“I think they’re aged 18, but they shouldn’t be drinking in those areas.
“The police had to remove around 60 of them who had set up tents in the woods near Worden Park a few weeks ago.
“People think they’re coming from Runshaw College, but they’re not.
“It’s happening during the evenings and the holidays.”
