There had been an increase recently in the number of vehicles being stolen to use in ram raids and other criminal activity, he said.
Tippett also suggested parking in a well-lit area, under a streetlight, if it was necessary to park on the street. He advised parking on a garage or on a driveway if possible.
The value of second-hand cars has risen due to supply chain disruptions and an increase in the cost of parts, Tippet said, meaning vehicles could be worth more than they were insured for.
"We're strongly encouraging car owners to check whether the value they have insured their car for still matches its current market value, in the event that it is stolen and never recovered or is recovered but is a total loss."
