The Metropolitan Police has expanded its fleet of high-powered electric motorbikes from five to 25 in what they say is an ongoing crackdown on phone snatchers and moped gangs across London.

The force said "targeted tactics" had helped drive down phone thefts across the capital by more than 13,000 offences over the past year.

Deputy Assistant Commissioner Louise Puddefoot said the e-motorbike fleet was "a powerful tool to stay one step ahead of criminals".
