Police say they have dismantled an international gang suspected of smuggling up to 40,000 stolen mobile phones from the UK to China in the last year. In what the Metropolitan Police says is the UK's largest ever operation against phone thefts, 18 suspects have been arrested and more than 2,000 stolen devices discovered. Police believe the gang could be responsible for exporting up to half of all phones stolen in London - where most mobiles are taken in the UK.
