Many cases involve criminals using other people’s identities to sell fake event tickets to friends and family

The total amount stolen by criminals who hack into people’s emails and social media accounts and then pretend to be them has risen by more than 400% in a year, official UK data shows.

In many cases, the scammers are hijacking people’s accounts in order to use their identity to sell fake event tickets - such as to sold-out gigs - to unsuspecting friends and family.
