Tim Stokes, chief superintendent Essex Police, warns that the police will face difficulties in evicting travellers and their supporters from Dale Farm:
"We have to be prepared for the worst-case scenario. We could face violent disorder, a drawn-out stand-off or peaceful resistance.
"We believe there will be people on the site who are intent on violence and we must police them rigorously and robustly. There are travellers on the site who value the presence of the supporters but there are also some who are fearful of them."
