Malicious pranksters have cost a restaurant thousands of pounds after booking almost every table for its busy Sunday lunch.
Alistair Myers, co-director of Rafters at Riverside House, in Derbyshire, said staff became aware of the stunt as they checked bookings ahead of the service.
They were shocked to find 80% of the tables had been booked with fake phone numbers and email addresses - enough for 109 seats.
