Leeds is one of the top three UK areas where mobile phone owners are most likely to have their device stolen, according to a new report by an insurance company.
Protect Your Bubble, which specialises in insuring modern technology, found that in London 18% of insurance claims are for theft of a mobile phone, the highest in the UK. Leeds was second, on 16%.
Stephen Ebbett, director of Protect Your Bubble, said: "Gadget owners can never be too cautious. Everyday we cart around hundreds, or even thousands of pounds' worth of high-tech gear, such as smartphones, tablets, cameras and e-readers.
"People can reduce their risk of being targeted by keeping their mobiles out of sight in public. Carry them in a pocket or bag with a zip, rather than your trouser pocket, or in your hand."
The survey covered the 30 largest towns and cities in the UK.
According to the data gathered by Protect your Bubble, users in their early 20s were the most likely to be victims of theft.
According to the National Mobile Phone Crime Unit, there are more than 250,000 reported cases of stolen mobile phones each year, with the unit encouraging users to install tracking apps to help trace a device after it has been stolen.
