London Bridge attack: Police name two of three men who carried out atrocity, one was known to MI5 for extremism
Butt known to police and MI5 and had been reported to anti-terror hotline
Two of the London Bridge terrorists have been named by Scotland Yard as Khuram Shazad Butt and Rachid Redouane.
Butt, a 27-year-old British citizen born in Pakistan, and Redouane, who claimed to be Moroccan-Libyan, both lived in Barking, east London.
Assistant Commissioner Mark Rowley said Butt was known to the security services, but there was no evidence of "attack planning" by him.
Mr Rowley said: "While formal identification is yet to take place, detectives believe they know the identity of the attackers.
"They believe two of the men are Khuram Shazad Butt and Rachid Redouane, both from Barking, east London.
"All three men were confronted and shot dead by armed officers within eight minutes of the first call.
"Inquiries are ongoing to confirm the identity of their accomplice," Mr Rowley added.
Redouane, 30, also used the name Rachid Elkhdar, claiming to be six years younger.
Butt was known to the police and MI5, and a member of public had reported him to an anti-terror hotline.
The investigation into Butt was started in 2015, "however, there was no intelligence to suggest that this attack was being planned and the investigation had been prioritised accordingly", Mr Rowley said.
He added: "Work is ongoing to understand more about them, their connections and whether they were assisted or supported by anyone else."
It is not yet known how the two men named knew each other.
Of the seven women and five men arrested since the attack a man and a woman have subsequently been released.
Referring to Butt, Mr Rowley said one of the three was part of an investigation "prioritised in the lower echelons of our investigative work".
Detectives would like to hear from anyone with information about the men, particularly places they may have frequented and their movements in the days and hours before the attack.
