A teenager has been detained after he circulated an explicit video of a 14-year-old girl to fellow pupils at her school.
The 16-year-old bullied the young girl for months, calling her "fat", until she relented and sent him a video of her stripping, as well as a naked picture of herself.
The teenager was sentenced at Peterborough Youth Court to 10 months at a young offenders' institute
The boy was told by the chairman of the bench his actions were "horrendous".
"What you did will have a lasting effect on her."
