Maghull Labour Action Team is working with residents to combat anti-social behaviour around south Maghull.
Householders have raised concerns about a spate of anti-social behaviour around Dover Road.
They complained that the problems increased after Lidl installed a new fence around its south Maghull store.
Concerns were raised to MP Bill Esterson and Maghull Town Council's Cllr Gwen Kermode whose parish ward covers Dover Road and Moorland Road.
Cllr Kermode said the issue has been raised with Maghull Neighbourhood Police, Sefton Council and Lidl.
Cllr Kermode said: "Maghull Labour Action Team, Bill Esterson and I have been contacted by a number of residents about this issue.
"They tell us that the problems of anti-social behaviour in the area increased when Lidl made alterations to the site.
"Anti-social behaviour in this area has been a problem in the past. At that stage we had one resident who said they were too afraid to leave the house because of fear of anti-social behaviour.
"Steps were taken then to alleviate the problem, including increased police patrols. We are determined to see steps taken to resolve the problem again."
MP Bill Esterson has taken the issue up directly with the supermarket.
Bill said: "I spoke to residents in and around Dover Road and many people raised concerns about anti-social behaviour in the area.
"We have taken the concerns to the police and Sefton Council.
"I have also made direct contact with Lidl to ask them to consider the impact on residents of the changes they made when the store was rebuilt recently.
"By bringing all the relevant bodies together, we hope to be able to eliminate the problem of anti-social behaviour around that part of Maghull.
"But we will obviously continue to monitor the situation. The cuts by the government of hundreds of police officers are of great concern and the fact that the anti-social behaviour team has been disbanded as a result of the cuts shows the folly of the cuts and the threat they pose to our community.
"People should not have to live with criminality of any kind, particularly on their doorsteps. This is an issue which we all need to work together to eradicate."
