An ITV investigation uncovered emails sent by former Great Yarmouth Charter Academy headteacher Barry Smith, who called pupils "detainees" when handing out detentions in his new role at Hackney New School, in London. One teacher, speaking anonymously, told ITV they were "encouraged" to give detentions or demerits if pupils were not smiling or "shuffled" when they walked. Shortly before his departure, the school denied he had been suspended, but said he had stepped back from day-to-day operations and was working "centrally on a curriculum project", although they refused to say more.
