Who is Khuram Butt? The London Bridge terrorist who appeared in Channel 4 documentary

One of the London Bridge terrorists appeared in a Channel 4 documentary about jihadis in the UK.

Khuram Butt, 27, unfurled an Islamic State flag with others on national television in the documentary last year and was also reported to police twice.

He was one of three killers, along with Rachid Redouane, 30, who drove a rented van into crowds and stabbed multiple victims on Saturday night.

Butt, from Barking, East London, is believed to have led the trio who ploughed into pedestrians before stabbing revellers in pubs and bars on Saturday night.

Nicknamed "Abz" and born in Pakistan, the former security guard, KFC worker and Transport for London employee from Barking, east London, was known to police after associating with extremist Muslim preachers.

In 2016, he appeared in the documentary "The Jihadis Next Door" alongside a notorious preacher as they prayed to an Islamic State flag in a London park.

A complaint was made about them and the documentary showed them in a confrontation with police on a footpath.

Police continue to investigate the weekend atrocity that left seven dead and 48 injured.

Officers made 12 arrests on Sunday as they raided several addresses including a tower block.

At least two individuals have claimed they reported Butt to the anti-terrorist hotline as his radical views emerged over the last two years.

The brother-in-law of the attacker told The Sun: "We haven’t been told what’s going on.

"We just want to grieve in peace."

It is understood the killer was a home-grown jihadi who came from Pakistan as a child but was brought up in the UK.
