( Telegraph ) Counter-terrorism officers secretly recorded an alleged Isil-inspired terror cell in Barking last month discussing how to use YouTube to plot a van and knife attack in London, The Daily Telegraph can reveal.
The investigators were monitoring the alleged extremist cell in the east London borough weeks before Saturday night’s attack in the capital, which left seven dead and 48 injured. The Islamic State group has claimed responsibility for the attack.
On Sunday police arrested 12 people, among them seven women – all of them in Barking and other parts of east London, where at least one of Saturday’s killers was believed to have lived. Those arrested were aged from 19 to 60.
Officers revealed that they fired an “unprecedented” 50 bullets at the attackers, who wore fake suicide belts to maximise panic and fear. Now The Daily Telegraph has learnt that police had been monitoring an extremist cell in that area since March.
