British police on Monday named two of the three attackers who killed seven people near London Bridge late on Saturday and injured dozens more, and said one of them was previously known to the security services.
London's Metropolitan Police said one attacker was Khuram Shazad Butt, aged 27. Butt was previously known to police and domestic spy agency, MI5 and was a British citizen who had been born in Pakistan, the police said.
“However, there was no intelligence to suggest that this attack was being planned and the investigation had been prioritised accordingly,” police said.
Butt appeared in a Channel 4 documentary entitled “The Jihadis Next Door” about British extremists that was broadcast last year, British media reported.
