London terror attacker Khalid Masood died from a single gunshot wound to chest, an inquest into his death was told today.
No police officers are under criminal or misconduct investigation over the shooting, the UK's police watchdog said.
The Independent Police Complaints Commissions investigator Christopher Lovett told the court its inquiry into the shooting will look at "organisational learning" and will highlight good practice.
Masood drove his car into pedestrians, killing three people, before fatally stabbing a police officer on March 22.
"The incident lasted approximately 82 seconds - from the first time the vehicle mounted the pavement until the attacker was shot by police. CCTV and other images obtained from witnesses provide a clear visual chronology of how the events unfolded," Lovett told the coroners court.
Masood, a British national born Adrian Russell Ajao, died at the scene after being shot by police.
The inquest into the 52-year-olds death was opened at Westminster Coroners Court and adjourned until May.
