On 2 February 2020, two people were stabbed in Streatham, London in what police termed a terrorist incident. The attacker, Sudesh Amman, was shot dead by the police. A nearby woman was slightly injured by broken glass as a result. At the time Amman was under active counter-terrorism surveillance, after having recently being released from prison on licence; he had been convicted in 2018 for disseminating terrorist material. Following the attack, the British government introduced the Terrorist Offenders Bill, a piece of emergency legislation intended to prevent those convicted of terrorist offences from being released early from prison.

Streatham is a district in south London, England. Centred 5 miles (8 km) south of Charing Cross, it lies mostly within the London Borough of Lambeth, with some parts extending into the neighbouring London Borough of Wandsworth.
