The Westminster attacker Khalid Masood was born Adrian Russell Ajao but took on a number of aliases before his murderous rampage targeting Britain’s parliament this week.
The 52-year-old man had a lengthy rap sheet but no known prior terrorism convictions, police said. He was shot by officers shortly after the attack and later died.
“Masood was not the subject of any current investigations and there was no prior intelligence about his intent to mount a terrorist attack,” Metropolitan Police said in a statement.
Masood was a British-born man who had a “range” of previous convictions for assault, possession of offensive weapons and other offenses, the statement said.
His first conviction was in November 1983 for criminal damage; his last conviction was in December 2003 for possession of a knife, police said.
Police say Masood plowed his car into a crowd on the iconic Westminster Bridge on Wednesday before he fatally stabbed a police officer outside Parliament.
The Islamic State claimed responsibility for the attack through its Aamaq News Agency and called the assailant, who was shot dead by police, a “soldier of the Islamic State.”
The claim couldn’t immediately be verified.
