Travellers have set up an unauthorised encampment at John Clare Park in Gunthorpe.
Three caravans were reported to Peterborough City Council yesterday (Wednesday).
A council spokesman said: “We have undertaken an initial visit and will start the process to move the group on.”
Another group of travellers are currently situated at a park in Beckingham, Orton Goldhay, despite being served an eviction notice.
The council said it will begin the eviction process if the group has not left by tomorrow morning (Friday).
