But, says UK Prime Minister Theresa May, he was a “peripheral” figure. There are so many such figures, they can’t possibly keep track of them all. And soon, courtesy her policies, there will be many more.

“Westminster attacker was British citizen known to authorities,” Sky News, March 23, 2017:

Eight are held after raids at six addresses in London and Birmingham as the PM insists the UK “will never waiver” to terrorism.

Theresa May has told Parliament that the Westminster attacker was a British citizen who was known to police and security services.

In a statement in the House of Commons, the Prime Minister said the attacker was a “peripheral” figure who had once been investigated by MI5 over concerns about violent extremism.

She said: “His identity is known to the police and MI5 and when operational considerations allow, he will be publicly identified.

“What I can confirm is that the man was British-born and that some years ago he was once investigated by MI5 in relation to concerns about violent extremism.

“He was a peripheral figure. The case is historic. He was not part of the current intelligence picture.

“There was no prior intelligence of his intent or of the plot.”
