A man shot dead by police after he stabbed people in south London had been released from prison in January.
Sudesh Amman, 20, was released about a week ago after serving half of his sentence of three years and four months for terror offences.
He was under active police surveillance at the time of the attack on Streatham High Road, which police believe to be an Islamist-related terrorist incident.
Three people were injured but none are in a life-threatening condition.
