London: Capital of laptop theft

Londoners had more than 15,000 laptop computers stolen last year - raising further concerns about the amount of sensitive information that may be falling into the wrong hands.

Last week silicon.com revealed the Metropolitan Police area saw by far the highest number of robberies and thefts of laptops during 2006 - more than 6,000. However, silicon.com can now reveal that when burglaries are included the total figure jumps to 15,389 - up nearly 20 per cent year-on-year.

That figure is equal to one laptop stolen in the Metropolitan Police area for every 500 Londoners last year alone.

Although laptop thefts are often an opportunist crime, with thieves striking when the victim's back is turned or their bag unguarded, security experts are warning that as criminals become more aware of the value of data on poorly protected laptops - which often exceeds any value there may be in selling the device second-hand - more targeted attacks could take place.

Although theft is nothing new, the number of laptops travelling around the capital on any given day is increasing significantly and creating a greater risk of data going astray. An opportunist thief will certainly find it easier to bag a laptop than get into a home or office and remove a desktop PC.

IDC reports the laptop market is currently growing at 16 per cent per year - lower than the rate of laptop theft in London (18.3 per cent).
