Police predicted Streatham attacker would strike ‘when not if’ on release

Officers had considered rearresting Sudesh Amman, who went on to stab two people, but decided there were insufficient grounds

Police predicted that a convicted terrorist would attack the public when he was released from prison, less than a month before he went on a knife rampage in south London, an inquest has heard.

MI5 and police officers discussing intelligence about Sudesh Amman said an attack would be a case of when, not if," two weeks before he was released from Belmarsh prison for terror offences in early January 2020.
