Thieves have stolen an estimated £1.7bn of possessions from Britons holidaying abroad in the last five years, it was revealed today. Some 11% of British adults have been the victim of theft while on breaks overseas, a survey by Sainsbury's Travel Insurance found. Yet only 51% of those who had something stolen reported the incident to local police, the poll of 2,000 British adults showed. The average value of the stolen items was £326 per person, with 5% of victims being robbed of valuables worth more than £1,000. Men have been more likely than women to be victims of theft with the most common form of theft being pickpocketing (21%), followed by theft from a car (17%) and bag snatching (16%). Also, 15% of victims had items stolen from their hotel room or villa. As many as 35% of victims had cash stolen, while 15% lost their camera to thieves and 14% had their mobile phone taken.
