LONDON -- The British man who killed four people during a London rampage had made three trips to Saudi Arabia: He taught English there twice on a work visa and returned on a visa usually granted to those going on a religious pilgrimage.
More details about attacker Khalid Masood’s travels, confirmed by the Saudi Arabian embassy in Britain, emerged Saturday amid a massive British police effort to discover how a homegrown ex-con with a violent streak became radicalized and why he launched a deadly attack Wednesday on Westminster Bridge.
The embassy said he taught English in Saudi Arabia from November 2005 to November 2006 and again from April 2008 to April 2009, with a legitimate work visa both times. He then returned for six days in March 2015 on a trip booked through an approved travel agent and made on an “Umra” visa, usually granted to those on a religious pilgrimage to the country’s Islamic holy sites.
The embassy said Saudi security services didn’t track Masood and he didn’t have a criminal record there.
Before taking the name Masood, he was called Adrian Russell Ajao, CBS News correspondent Jonathan Vigliotti reports. He was known for having a violent temper in England, had been convicted at least twice for violent crimes and was once investigated for violent extremism.
But by 2017 -- at the age of 52 -- he’d fallen off the radar, settling down with his wife and three children on a quiet street in the central English city of Birmingham, Vigliotti reports. His neighbors said he loved to garden.
The neighbors said he abruptly packed up and moved his family out three months ago, Vigliotti reports. They said they hadn’t heard from him or seen him until the attack.
On Wednesday, Masood drove his rented SUV across London’s crowded Westminster Bridge, striking pedestrians. Then he jumped out and stabbed to death police officer Keith Palmer, who was guarding Parliament, before being shot dead by police.
In all, he killed four people and left more than two dozen hospitalized, including some with what have been described as catastrophic injuries. The Islamic State of Iraq and Syria, or ISIS, has claimed responsibility for the attack, calling him a “solider” who responded to its demands that followers attack countries in the coalition fighting ISIS in Syria and Iraq.
British officials said security at Parliament will be reviewed after new footage emerged that showed the large gates to the complex were left open after Masood rushed onto the grounds. There are concerns that accomplices could have followed him in and killed even more people. The footage from that day shows pedestrians walking by the open gates and even a courier entering the grounds.
Former Metropolitan Police commissioner Ian Blair told the BBC that changes to the “outer soft ring” of Parliament’s security plan are likely in the aftermath of Masood’s attack.
The new footage follows earlier video that showed slight delays and confusion during the evacuation of Prime Minister Theresa May from Parliament as the attack unfolded.
Masood, who at 52 is considerably older than most extremists who carry out bloodshed in the West, had an arrest record in Britain dating to 1983. In 2000, he slashed a man across the face in a pub parking lot in a racially charged argument after drinking four pints, according to a newspaper account. Masood’s last conviction, in 2003, also involved a knife attack.
The British press quoted people who had contact with Masood over the years describing him as a man who seemed to lose control at a moment’s notice. One victim, Danny Smith, told The Sun newspaper that Masood had stabbed him in the face with a kitchen knife after an argument just three days after they met.
Hundreds of British police have been working to determine his motives and if he had any possible accomplices. Two men, aged 27 and 58, remain in custody for questioning after being arrested in Birmingham. Authorities haven’t charged or identified the men.
Seven others who had been arrested in connection with the investigation have been set free. A 32-year-old woman arrested in Manchester and a 39-year-old woman arrested in east London have been released on bail.
Police are scouring Masood’s communications systems, including his possible use of the encrypted WhatsApp device, to help determine if he had any accomplices in the attack.
Details about how he became radicalized aren’t clear, although he may have become exposed to radical views while an inmate in Britain or while working in conservative Saudi Arabia. It’s also not clear when he took the name Masood, suggesting a conversion to Islam.
