Police have identified all three attackers responsible for the London Bridge and Borough Market attacks on Saturday night.

One of those attackers, Khuram Shazad Butt, was a known extremist and had even appeared in Channel 4 documentary “The Jihadis Next Door.”

The 27-year-old father-of-two was the ringleader of the trio and, according to the BBC, had been reported to police by neighbours who say he used to watch clips of the American hate preacher Ahmad Musa Jibril.

In the Channel 4 documentary, Butt, often called Abz, can be seen in Regent’s Park in central London with a group of worshippers unfurling an ISIS-style flag.

They proceed to pray before police are called to the scene by a concerned member of the public.

The group become agitated and shout down the officer when they are told they are being “detained for the purpose of a search.”

London Bridge attacker Butt then speaks to the camera.

“The only English, white person, who’s a non-Muslim, who was part of our group, but because he’s white and he’s English he can go,” he says, presumably referring to cameraman Jamie Roberts who spent two years documenting radicalised preachers.

“But all of us that were just praying, we have to stay.”

Despite being known to the police and MI5, the Met police say that there was no intelligence to suggest that the attack was being planned.
