A man is fighting for life after being stabbed on a street in Woolwich on Sunday night.
Officers were called to Mayplace Lane just after midnight on Sunday, where they found a 19-year-old man with knife injuries.
He was rushed to hospital, where he remains in a life-threatening condition. His family have been informed.
Two males, both 15, were arrested nearby on suspicion of attempted murder.
They have been bailed pending further enquiries.
