Police in Dubai have arrested a group of “high tech” car thieves who had them baffled for quite some time. The problem was that the stolen cars seemed to disappear completely. Once the cars were stolen, they were never turning up again anywhere. The trick, apparently, was that the thieves had bought previously totaled cars of the same model abroad. Then, they swapped out the car’s computer systems and any identifying information with the totaled cars. Then, the cars had every appearance of being the cars that had been bought from abroad, rather than the ones that were stolen
