LONDON (AP) -- British police investigating the savage killing of an off-duty soldier in London have arrested three more suspects.
Scotland Yard said counter-terrorism officers arrested two men, aged 24 and 28, at a residential address in southeast London.
A third man, 21, was arrested separately on a London street at the same time.
Officers have already detained four others in connection with the murder of 25-year-old soldier Lee Rigby, who was stabbed to death while walking outside the Royal Artillery Barracks in the Woolwich, south London, on Wednesday afternoon.
Police said Saturday they used a stun gun on two of the suspects. All three were detained on suspicion of conspiracy to commit murder.
