Detectives working for the Metropolitan Police in London say they think Westminster attacker Khalid Masood acted alone.
They have admitted his motive for the attack, in which a police officer and three pedestrians died and dozens were injured, may never be known.
“Even if he acted alone in the preparation, we need to establish with absolute clarity why he did these unspeakable acts to bring reassurance to Londoners and to provide closure for the families of those killed and the victims and survivors of this atrocity,“said Deputy Assistant Commissioner Neil Basu.
“We must all accept there is a possibility we will never understand why he did this. That understanding may have died with him.”
“Whilst the attack lasted only 82 seconds, it will remain in the memories of many forever. The thoughts of all those working on this investigation are with those so deeply affected.”
Officers have confirmed that the Khalid Masood’s rampage across Westminster Bridge and into the Houses of Parliament lasted only 82 seconds.
