The man who mowed down pedestrians on a London bridge and fatally stabbed a police officer on Parliament's grounds was born in Britain and was known to intelligence services, the prime minister said Thursday.
He's now been identified as 52-year-old Khalid Masood who had once been investigated for extremism links, but was considered a peripheral figure.
Masood was known to police and most recently had a run-in with the law in 2003 for possession of a knife.
Police said there had been no prior intelligence about Masood's intention to carry out an attack.
Theresa May, who didn't disclose the man's name, said that he was once investigated for extremism links, but was considered a peripheral figure.
May delivered a defiant message to the House of Commons, declaring simply: "We are not afraid."
