A number of New Orleans police patrol cars have been spotted in Houston since Hurricane Katrina struck — several of which are now being stored in HPD parking lots, officials said. Details about how the patrol cars arrived in Houston remained sketchy , more than a week after the devastating storm caused major flooding in the city. "To our knowledge, (the patrol cars) have been driven by New Orleans police officers," said Lt. Robert Manzo, an HPD spokesman.New Orleans police commanders are aware that several of their patrol cars are now in Houston, Manzo said. "We were told not to stop them and we were told that these cars were not reported stolen," Manzo said. The patrol cars apparently were taken by New Orleans police officers as they evacuated the city, officials said. "That was the only mode of transportation," Manzo said. New Orleans police officials "are not interested in pursuing any charges against (the drivers.)"
