Travellers are currently being evicted from the former Wickes site in the town centre.

Around 20 police officers are currently dealing with the incident.

Eyewitness Kelly Fox told the Observer: "There was 10 police vans, cars and even a lorry.

"I have never seen that many come out from the police station before."

Police are working with partners to remove an unauthorised traveller encampment in Lower High Street.

Officers are using powers under Section 61 of the Criminal Justice and Public Order Act and work is on-going at this stage.

Superintendent Sue Jameson said: “Our main priority is to ensure the safe removal of all people from this site.”
