The 28 year-old British man who killed two people in a stabbing spree on London Bridge had previously been convicted of terrorism offenses and was released from prison last year.
Sporting a fake suicide vest and wielding knives, Usman Khan went on the rampage on Friday (November 29) afternoon at a rehabilitation conference in the area.
He was wrestled to the ground by bystanders and then shot dead by police.
Khan's family hails from Pakistan-controlled Kashmir.
He was convicted in 2012 for his part in an al-Qaeda-inspired plot to blow up the London Stock Exchange.
But was released in December 2018 - subject to conditions.
Friday's attack, just 13 days before a general election, prompted political leaders to scale back campaigning.
Their focus is likely to shift from Brexit and the health service to crime.
(SOUNDBITE) (English) BRITISH PRIME MINISTER BORIS JOHNSON, SAYING: And my thanks go, first of all, to the emergency services, the police for their bravery and their professionalism.
And to repeat again, my thanks to those members of the public who put themselves in harm's way to protect others.
And I think they represent the best of our country and I thank them on behalf of the rest of our country." A video posted on Twitter showed police dragging one man off the suspect before an officer took careful aim.
Later in the video, two shots ring out and the man stops moving.
During the 2017 election campaign, London Bridge was the scene of another attack.
Three militants drove a van into pedestrians and then targetting people in the surrounding area, killing eight.
The incident focused attention on cuts to policing since the governing Conservatives took power in 2010.
