Nine people have been arrested in Athens, accused of selling stolen luxury cars in a racket police believe has cost the state hundreds of thousands of euros in lost car duties and could involve public servants. Police said yesterday that the suspects are part of an international ring that has been operating in Greece over the last two years by selling stolen cars to car dealerships. The vehicles, either from Greece or imported from Spain, were brought into the country with forged customs documents in order to avoid paying the necessary taxes. The cars were then registered under non-existent names. Police also found that there were no records of the vehicles at the Eastern Attica Prefecture transport services, indicating that civil servants may have been involved in the operation.
