Travellers have entered land to the north of West Parade, Worthing.
The council has directed the travellers to leave, and visited the site today to assess the situation and ascertain the travellers’ needs, the environmental impact of their presence and the loss of public amenity.
The Police will regularly visit the site.
A resident of Anscombe Road, who did not want to be named, said: “They have taken over and it is not nice for residents.”
The resident said there were currently around eight caravans at the site.
