Three men arrested in south London on Saturday in connection with the murder of Drummer Lee Rigby have been released on bail, Scotland Yard has said. The men, aged 21, 24 and 28, who were arrested on suspicion of conspiracy to murder, have been bailed to return later to a police station in London. Two men arrested on suspicion of murder at the scene of Wednesday\'s killing in Woolwich remain in custody. A 22-year-old man arrested on Sunday in north London is also still being held. His arrest by counter-terrorism police in the Highbury Grove area on suspicion of conspiracy to murder was the ninth arrest as part of the investigation. The two murder suspects, Michael Adebolajo, 28, and Michael Adebowale, 22 , both Britons of Nigerian descent , remain in custody in hospital in a stable condition after being shot and wounded by police at the scene after the killing. On Sunday the British Foreign Office confirmed it had given consular assistance to suspect Adebolajo when he was arrested in Kenya in 2010. Kenyan government spokesman Muthui Kariuki told the (BBC) News he was believed to have been preparing to fight with Somali militant group al-Shabab. Adebolajo was then handed over to \"British security officers\" when it emerged he was a UK citizen.
