Enforcement action is underway to remove travellers illegally encamped in Sudbury.
Several caravans have pitched camp in Claremont Avenue, near a housing estate and children's play area, Suffolk police said.
A Suffolk Constabulary spokesman said: "We are aware of a traveller camp close to a children's play area in Claremont Avenue in Sudbury.
"We are working with our partner agencies to bring a resolution to the situation."
Babergh District Council have been approached for comment and a spokesman for Sudbury Town Council said: "We are aware of the traveller encampment at Claremont Avenue and our community warden team will be working with partner agency's tomorrow to resolve the issue."
This is the third illegal camp to appear in Suffolk in the last four weeks, with two groups of caravans arriving in Ipswich in April.
Travellers camped illegally at the Anglia Retail Park and the Copdock Park and Ride.
