An Islamic fanatic who starred in a Channel 4 documentary with London Bridge terrorist Khuram Butt has been arrested for the same attack.
Ricardo McFarlane, 29, was taken into custody after a raid by anti-terror police in east London last week.
He is one of seven suspects that are being quizzed by detectives in relation to the horrific attacks on London Bridge and Borough market on June 3.
Eight people were murdered and 48 injured when terrorists Khuram Butt, Rachid Redouane and Youssef Zaghba mowed people down in a van before going on a stabbing frenzy.
McFarlane appeared in the TV documentary the Jihadi Next Door with Butt, when it aired last year.
Footage from the show, which got 1.2million viewers, showed him praying with a group in Regents Park, after they had angrily confronted worshippers outside a mosque in central London.
McFarlane is the first of those featured in the film to be arrested since the attack. Butt was shot dead by armed police at the scene.
This is not the first time that McFarlane, a Muslim convert, has been fallen foul of the law for his extremist views.
In February 2013 he was jailed for his role in a trio who formed a ‘Muslim Patrol’ and terrorised members of the public as they tried to promote Sharia Law.
McFarlane, Jordan Horner and Royal Barnes were jailed for a total of two years and ten months for touring east London harassing people they deemed to be ‘non-believers’.
The three men were slapped with a five-year anti-social behaviour order banning them from distributing material about Sharia Law to the public, or even meeting each other.
Judge Timothy Pontius, also banned them from associating with hate preacher Anjem Choudary.
The judge said: ‘With the public interest in mind and the safety of individual members of the public in particular, it seems to me essential that these orders should be granted to run for that period of time.’
