LONDON (Reuters) - British police said on Monday they had found no evidence that Khalid Masood, who killed four people in an attack on parliament last week, had any association with Islamic State or al Qaeda, but he was clearly interested in jihad.
Masood drove a car through a crowd of pedestrians on Westminster Bridge, killing three and injuring about 50, then ran through the gates of parliament and fatally stabbed a police officer before he was shot dead.
Neil Basu, senior national coordinator for UK counter-terrorism policing, said there was no evidence that Masood had been radicalized in prison in 2003 and it was pure speculation to suggest that had happened.
Masood, 52, was British-born and had several previous convictions for offences such as grievous bodily harm, possession of a knife and disturbing public order. He had not been convicted of any terrorism offense.
“His attack method appears to be based on low sophistication, low tech, low cost techniques copied from other attacks, and echo the rhetoric of IS leaders in terms of methodology and attacking police and civilians, but at this stage I have no evidence he discussed this with others,” Basu said in a statement.
“I know when, where and how Masood committed his atrocities, but now I need to know why,” he said, appealing to anyone who may have been in contact with him on the day of the attack to come forward.
Masood was born Adrian Russell Ajao and on Monday his mother Janet Ajao issued a statement saying she was “shocked, saddened and numbed” by his actions.
“I do not condone his actions nor support the beliefs he held that led to him committing this atrocity,” she added.
An inquest into the deaths of the four victims will open on Wednesday and adjourn to give the police time to finish their investigation. A separate inquest for Masood will open and adjourn on Thursday.
Interior minister Amber Rudd said on Sunday that technology companies should cooperate more with law enforcement agencies and should stop providing “a secret place for terrorists to communicate” using encrypted messages.
Media have reported that Masood sent an encrypted message moments before the attack.
“There has been much speculation about who Masood was in contact with immediately prior to the attack,” Basu said. “All I will say on this point is that Masood’s communications that day are a main line of enquiry.”
