A teenager has been charged after an alleged assault on a headmaster which was captured on another pupil's mobile phone, according to police. The so-called "happy slapping" attack happened during lunchtime in a school canteen in the Borders.
Footage from a pupil's mobile phone is said to show another teacher intervening to stop the incident.
Police said a 15-year-old had been reported to the Children's Panel.
Scottish Borders Council declined to comment because of the Lothian and Border Police inquiry but said there were rules in place regarding mobile phones in their schools.
