A man 'with mental health issues' was in police custody on Wednesday night after he went on a rampage with a knife in central London, killing a woman her 60's and injuring five other people.
The suspect was taken to hospital before being taken to a south London police station where he was subsequently formally arrested on suspicion of murder. Several London streets in Bloomsbury remain taped off as Police CIS teams scour the area for clues.
Counter-terrorism police have been drafted in, however, officers also said "mental health is a significant factor" in the case and a source said this morning that terrorism is looking "less likely" as a motive.
The suspect was described as a 19-year-old male.
The wounded included three men and two women.
"However we are keeping an open mind regarding the motive and terrorism remains one line of inquiry being explored," Met Police Assistant Commissioner Mark Rowley added.
Rowley said Londoners would wake up on Thursday to a noticeably increased police presence all over the Capital as what he termed a precautionary measure.
