Police say they are monitoring the situation after travellers descended on a Stevenage park last night.
Officers were called just after 8pm on yesterday to reports of a number of caravans driving onto Canterbury Park, which can be accessed from Ripon Road and is also close to Canterbury Way and Great Ashby Way.
A force spokeswoman said the landowners are aware and officers are continuing to monitor the situation.
A spokeswoman for Stevenage Borough Council, which has powers to serve an eviction notice, said the authority visited the travellers today to ask them to move on as they are on public land.
