According to the Endsleigh Insurance motor theft index, Hull is the most dangerous place to park a car in Britain for the second year in a row.
In second place was Nottingham followed by the West Yorkshire town of Bradford, Manchester, and the South Yorkshire town of Doncaster.
However, Humberside Police denied that crime is rising in Hull, instead pointing to evidence that motor theft has actually reduced over the past year.
The Insurance company stated that there has been a national reduction in car theft over the last year although there are still some towns that pose more of a theft, especially cities found in North England and the Midlands.
On the flip side of the index, Swindon was found to be the safest place to leave a motor vehicle followed in second place by Cheltenham. Rounding out the top five safest places to leave a motor vehicle were Southampton, Solihull, and Bangor.
Endsleigh Insurance compiled the figures by looking over the last three years of motor claims from tens of thousands of British motor insurance policy holders.
Stuart Wartalsi, an employee of the company, stated that the risk of theft is the highest after the holidays when cars are targeted that have cameras, DVDS, satnavs, and laptops inside of them.
Wartalsi advised motorists that they should always hide any valuables under the seat, in the trunk, or out of sight somewhere within the vehicle and that a car should be outfit with an alarm even while parked in well lit areas.
