　　Passage 7

　　The recent increase in car theft has alarmed the police who are looking for what they now believe must be a well-organized gang of professional car thieves. Most of the thefts have taken place in the rich residential areas round Southwell Park, where last week alone 22 car thefts were reported to the local police. Of these only one has been found, abandoned in Rockinghill Palace Road 20 miles away. The others have still not been found except for one which had been falsely reported missing. The owner later admitted that he had forgotten where he had parked it a few days before. An interesting aspect of the thefts is that nearly all the missing vehicles had been taken from locked garages. The owners now admit that they my have left the car doors unassumed that the gang find it easier to break into garages where vehicles are often left unlocked at night than into locked cars parked on the roadside in daytime or at night. They advise car owners to lock up their cars even when they are kept in locked garages.
