For anybody that's built or renovated a home, the sight of tradesmen wandering around your house isn't an unusual one. When Sally Ryan was approached by one Irish and one English lad who told her that they were there to seal her driveway, at first she thought that they had been arranged by the builders of her new house on Hobby's Yards Road just out of Blayney. The builders though knew nothing of it and when Mrs Ryan thought about what they were offering, her suspicions were raised. "They turned up and said that they had some leftover asphalt from the road," she said.

Mrs Ryan said that they claimed that they were working for council as outside contractors. A quick phone call confirmed her suspicions. "Council said definitely not, so I then called Australian Asphalt who said that these guys were doing it all over the country and were ruining his business," she said. The next call was to the police who had not received any calls regarding this group operating in the area and decided to pay a visit to the Ryan's home to investigate. "When they saw the police car the whole crew high-tailed it," she said. The police pursued the pair and stopped them soon after. Duty officer for Chifley Local Area Command Inspector David Abercrombie said that residents need to be wary of the pair. "When spoken to by the police one of them was found to be aggressive towards police and the other was playing dumb," he said. "They were given a move on direction by police to leave the area and not to return as no offence had actually been committed as it was interrupted by the police." "People need to be aware that these people are in the area and are floating around purporting to be working for Australian Asphalt who have nothing to do with them. "These guys are doing some very shonky work that they're claiming payment for, if given the opportunity to do the work, which isn't certified at all."
