Travellers arrived at the Commons Car Park in Harborough yesterday.
The travellers who are currently taking up approximately 15 parking spaces in the car park behind the Co-Operative supermarket are still there today.
There are four mobile homes and a number of vehicles that appear to belong to the travellers who are sited there.
Vehicles could be seen coming in and out of the site today.
The Mail was contacted by a person who spotted the travellers there last night. They also said that they saw police at the site.
