White Muslim convert Richard Dart and a former police community support officer were among six people arrested for allegedly plotting a terror attack in Britain.
Richard Dart, 29, is a white Muslim convert who featured in a BBC documentary last year filmed by his own brother about his conversion.
Richard Dart, who was radicalised by the cleric Anjem Choudary, was held following police raids in east and west London.

Mr Dart, 29, the son of Dorset teachers, featured in a BBC documentary last year filmed by his own brother about his conversion. During the film, called My Brother the Islamist, he was seen protesting about British soldiers in Afghanistan and accused them of being “murderers”.
