The man police say was responsible for the Westminster attack has been formally identified as 52-year-old Khalid Masood but his birth name is Adrian Russell Ajao, born in Kent and most recently lived in the West Midlands.
Masood is also believed to have lived at various times in Crawley, West Sussex, and Rye and Eastbourne, both in East Sussex, as well as Luton and east London.
The Metropolitan Police says he was also known by a number of aliases.
The BBC believes that Masood hired the car used in the attack earlier this week from the Spring Hill branch of Enterprise in north Birmingham. He described his profession as a “teacher” – although the BBC has been able to confirm that he never worked as a qualified teacher in English state schools.
Within an hour of hiring the Hyundai, he is thought to have contacted the company to say he no longer needed the car. What happened next is completely unclear – until he drove north across Westminster Bridge, ploughing into pedestrians on the western pavement.
“Masood was not the subject of any current investigations and there was no prior intelligence about his intent to mount a terrorist attack,” Scotland Yard said.
“However, he was known to police and has a range of previous convictions for assaults, including grievous bodily harm, possession of offensive weapons and public order offences.”
Masood’s first conviction came when he was 19-years-old in November 1983 for criminal damage. His last conviction was in December 2003 for possession of a knife. He had never been convicted of a terrorism offence.
In her statement to MPs, the prime minister said that the attacker was British born and that “some years ago” he was “once investigated in relation to concerns about violent extremism”.
She went on: “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.”
