Police have arrested a seventh Muslim in connection with a suspected plot to carry out a major terrorist attack on British soil

A 22-year-old woman has been detained at an address in Hackney, east London. She was arrested on suspicion of the commission, preparation or instigation of acts of terrorism under the Terrorism Act 2000, a spokesman for the Metropolitan Police said. The arrest, by officers from the Met's Counter Terrorism Command, follows six others. The woman is in custody at a south-east London police station. Previously British Muslim convert Richard Dart, 29, was one of the six people arrested over the suspected terror plot. Dart, who changed his name to Salahuddin al-Britani after converting to Islam, is believed to have been one of three people detained in Ealing, west London, and was arrested in the street. He appeared in a BBC documentary, My Brother The Islamist, made by his stepbrother Robb Leech in 2011, which described how Dart, originally from Weymouth, Dorset, had been converted by controversial Islamic cleric Anjem Choudary. In the documentary he spoke of his support for jihad and sharia law. The others detained in Ealing were a 21-year-old man and a 30-year-old woman held at separate home addresses. Three men living just over a mile from the Olympic site in Stratford, east London, were also arrested. The men, aged 18, 24 and 26, who are believed to be members of the same Bangladeshi family, were detained in a raid on their home.
