A couple's car was stolen while they were taking a dip in Lake Wakatipu at Frankton at noon on Thursday.
Senior Constable Chris Blackford, of Queenstown, said the car keys were wrapped in a towel on the beach. The couple were in the water for only about 15 minutes, but when they returned they found the keys and car gone.
The car is a green Subaru Legacy station wagon with the number plate ZK9450. If anyone has information on the matter, please contact the police.
