The man suspected of carrying out a knife attack in north London was previously referred to the Government’s counter-extremism programme, police have said.
Scotland Yard said a referral made to Prevent in 2020 was closed in the same year.
Police across the country have stepped up patrols in response to the attack that saw two Jewish men – 34-year-old Shloime Rand and 76-year-old Moshe Ben Baila, named locally as Moshe Shine – taken to hospital after being stabbed.
A 45-year-old man, said by police to be a Somali-born British national, was arrested following the incident.
Home Secretary Shabana Mahmood said the man came to the UK “lawfully as a child” in the 1990s.
