"The other car had its motor running, and lock and glass broken," he said.
Because he had left his wallet in his car, he decided to check his bank balance on his phone and found his account in overdraft, having been drained of about $85. When he called his bank, he was told of two transactions - at a Manurewa service station at 2.16pm, and another in Clevedon 21 minutes later. As he was talking to the bank, his brother-in-law was on the phone to police, relaying details of the car's movements.
The pair were surprised and pleased to hear on Friday night that the car had been found, but disappointed to be told it had crashed.
Mr Mirza's brother-in-law, who wanted to be known only as Rasheed, said they were told there had been a high-speed car chase but were not told where. He gathered from the police there might have been more than one person in the stolen car, and feared initially that the occupants would have ended up in hospital. But he said the police told him "No, in jail".
An officer in charge of the case, who has been off duty over the weekend, could not be reached to provide more details.
Mr Mirza said that when he visited the Counties-Manukau police station on Saturday, he was told the driver of his stolen car had been arrested.
Asked whether the theft had altered his view of New Zealand, he said: "To some extent it is safe, but crime can happen anywhere."
