Residents may have stopped travellers from building a new illegal caravan site in their Essex hamlet after chasing off men allegedly posing as broadband workers to carry out survey work.Locals in Willows Green in Essex were put on red alert last week after it emerged that Edward Myles Anthony Connors, an Irish traveller from a family with a history of unauthorised development, had paid £150,000 cash for a nearby field.They were already reeling after a 12-pitch traveller caravan site was illegally developed by different travellers on another field just 300 yards away over the May Day bank holiday weekend.They have maintained a constant watch over the land ever since and reported any suspicious activity to Uttlesford District Council. Thanks to their efforts, the council secured an emergency High Court injunction banning any development. On Saturday, Mrs Justice Alison Foster issued a temporary injunction which bans Mr Connors and 'persons unknown' from carrying out any form of development at the site without planning consent until a full hearing can take place. Fears were heightened last Wednesday when signs went up by the field saying that the road next to it would be closed from May 26 to May 31 to allow a water company to carry out work to connect a water supply for 'drinking troughs for horses'.That same day, a local woman watched a group of men turning up in a white van seemingly surveying the site. She left her home and confronted them while recording the moment.In audio obtained by the Daily Mail, a man with an Essex accent is heard claiming he is doing work for a broadband company and that residents should have been notified. He says he will speak to his supervisor and return with paperwork within ten minutes.A photo of one of the fake workmen, who appeared in Willows Green last week The men went away after they were confronted by a local resident A traveller site appeared over the May bank holiday weekend in the village of Willows Green, EssexHowever, he never returned, and the broadband company in question has confirmed to the Mail that none of its teams were in the area at the time. The woman told the Mail afterwards: 'They looked like they were marking out an entrance but after I spoke to them they just left and never produced any paperwork.' DVLA checks on the pair's vehicle show it was untaxed since April 30 and neither of them were wearing uniform. The woman confirmed she had passed information about the incident to the council before the injunction was granted on Saturday. She added: 'We did it. We told the council everything that had happened near the field and now an injunction is in place.' The first plot at Willows Green was illegally developed in a 'military-style' operation that began on May Day. Within hours of the council closing, an army of workers and around 30 vehicles pulled onto the land.Using lights and generators, diggers began turning over grass ready for hardcore and asphalt.The May bank holiday development was part of a trend that sees travellers build unauthorised developments over long weekends when council enforcement teams are at home. They then apply for retrospective planning permission in a bid to make them permanent. Uttlesford District Council failed to act to stop the first site despite being warned that travellers were planning to import thousands of tonnes of hardcore to the field, but the authority has been praised for securing the injunction preventing building work on the second field.
