"I ain't no terrorist" - Usman Khan speaks in file interview from 2008 - BBC

According to the BBC, Khan was interviewed in Stoke-on-Trent by BBC Midlands in 2008 following a raid on his address by anti-terror police.

Nine years before Usman Khan killed two people in a stabbing spree on London Bridge, he was overheard by British security services discussing how to use an al Qaeda manual he had memorised to build a pipe bomb.

It was a snippet of conversation, along with other intelligence about a plot to bomb the London Stock Exchange, that prompted British police to arrest Khan - then 19-years-old - and a group of older men on Dec. 20, 2010.

Sentenced to a minimum of eight years in prison in 2012 with a requirement that the parole board assess his danger to the public before release, he was set free in December 2018 - without a parole board assessment.
