A friend of one of the suspected attackers says he had reported him to the anti-terror hotline, but no action was taken.
The man, who asked not to be named, told the BBC’s Asian Network that the pair had spoken about previous attacks and he was shocked at what he had heard.
“We spoke about a particular attack that had happened and … he had a justification for anything, everything and anything,” he said. “That day I realised that I need to contact the authorities.”
But the friend claims the suspected attacker was not arrested and was allowed to keep his passport.
“I phoned the anti-terrorist hotline and spoke to the gentleman,” he said. “I told him about our conversation and why I think he has been radicalised.
“I did my bit, but the authorities didn’t do their bit.”
The BBC has asked Scotland Yard for a response.
Why did police not do anything? Were they stopped by MI5 secret police, because the perpetrator was an asset of MI5, connected to war in Libya, Syria or elsewhere? Like the perpetrator of the Manchester Ariana Grande concert attack was one of Manchester jihadi child soldiers going to NATO’s Libya war, were stopped by police, after which MI5 overruled police?
