London Bridge Terrorist was in Channel 4 Documentary about British Jihadis

One of the London Bridge terrorists reportedly appeared in a TV documentary about jihadis in Britain, even being filmed arguing with police officers after unfurling an Isis flag in a park.

The 27-year-old from Watford, who has not been named at the request of counter-terror police, was allegedly caught on camera during the filming of the Channel 4 show.

Alongside two notorious extremist preachers, the man was seen unfurling the ‘black standard of Isis’ in public. The preachers were already well known to police and intelligence officials because of their extremist views.

Amid a series of revelations in the wake of the attack, it was claimed an acquaintance of the suspect had reported him to the anti-terror hotline after he became radicalised by extremist videos on YouTube.

It was also claimed that, two years earlier, police were warned that the suspect was trying to radicalise children in a local park.

The man is believed to be one of the three attackers behind Saturday night’s carnage.

Seven people were killed and 21 left fighting for their lives after the three men drove repeatedly into a busy crowd on London Bridge, before continuing their horrific attack by stabbing people in the city’s busy Borough Market bars and restaurants.

Police marksmen shot all three suspects dead within eight minutes of the emergency services being called to the scene.

In a speech delivered outside Downing Street in the wake of the attack, Theresa May said that ‘enough is enough’.

‘There is – to be frank – far too much tolerance of extremism in our country,’ she said, before pledging to tackle ‘safe spaces’ for jihadis both online and ‘in the real world’.

Amid calls for the general election to be cancelled, the Prime Minister also confirmed that the vote would go ahead on Thursday as planned.
