LONDON (AP) - British police say two more people have been arrested by officers investigating the hacking death of a UK soldier in London.

Scotland Yard said counterterrorism officers arrested a man and a woman - both 29 - on Thursday on suspicion of conspiracy to murder. Both suspects are in custody at a south London police station.

Two suspects shot and arrested by police at the scene Wednesday - a 22-year-old man and a 28-year-old man - remain hospitalized in stable condition with injuries that are not life-threatening, police added.
