Failures by British police and intelligence services were partly responsible for a terror attack at Fishmongers’ Hall in London, an inquest jury has found.
Usman Khan killed two people in November 2019 at a prisoner rehabilitation event near London Bridge. He was chased down by bystanders and later fatally shot by police.
The inquest jury concluded there was "a lack of accountability and deficiencies in management" by authorities overseeing Mr Khan after his release from prison.
They said authorities were blinded by his “poster-boy” image as a rehabilitated prisoner, when in fact he remained a committed extremist.
The inquest jury also concluded that the two victims, Jack Merritt, 25, and Saskia Jones, 23, were unlawfully killed.
Mr Khan stabbed the two at an event run by the prisoner rehabilitation program Learning Together. Mr Merritt worked for the program and Ms Jones was a volunteer.
Mr Khan was arrested in 2010 for being part of an Al Qaeda-inspired plot to set up a terrorist training camp in Pakistan. He was given an "indeterminate" sentence that specified he could only be released when he was judged not to be a danger to the public.
He appealed, and the sentence was fixed at 16 years. Like many British inmates, he was released after serving half that time, in December 2018.
A prison psychologist warned at the time that he was more dangerous to the public than when he entered prison, and provided a list of warning signs for authorities to monitor.
The domestic intelligence agency MI5 passed on uncorroborated intelligence to police that Khan was preparing to return to his “old ways” and aspired to carry out an attack. MI5 and counterterrorism police launched an investigation into Khan which was under way at the time of the attack, but Khan’s probation officer and the panel supervising his release were unaware of it.
He was allowed to travel alone to London to attend the Learning Together event, where he strapped knives to his hands and launched his attack.
The jury praised “astonishing individuals,” including other former prisoners attending the event, who fought back and disarmed Khan, using items including a fire extinguisher and a narwhal tusk displayed in the hall. Armed police soon arrived and shot Khan, who wore a suicide belt that turned out to be fake.
In a statement, the inquest jury expressed “heartfelt condolences to the families of Saskia and Jack, and to all who love and miss these two wonderful young people. They clearly touched the lives of so many, ours included.”
“The world lost two bright stars that dreadful day,” the jury said.
