Police were called to Chelsea Bridge Road, west London, on Saturday morning after receiving reports that a man was armed with a screwdriver and shouting. He was rescued from the water and taken to hospital in a critical condition.
The IOPC, the police watchdog, said on Sunday the man, aged in his early 40s, had died in hospital and that an inquiry was under way.
IOPC director Steve Noonan said: “We have spoken to the man’s family to express our sincere condolences and explain our involvement.
"Our sympathies remain with them at this terrible time. Our independent investigation is under way into the police actions at the bridge and we have begun gathering and reviewing evidence.”
I understand that there are always concerns about incidents in which people come to harm having been in contact with police.
Detective Chief Inspector Rory Wilkinson
The watchdog said: “We are investigating contact Metropolitan Police officers had with a man on Chelsea Bridge yesterday morning (Saturday) prior to him entering the River Thames.
“He was subsequently rescued from the water and was taken to hospital in a critical condition. The man, in his early 40s, sadly died in hospital on Saturday evening.
“We were notified by the Metropolitan Police on Saturday and sent investigators to the scene and to the police post-incident procedure to begin our investigation. Initial information indicates that officers were responding to reports of a disturbance when they encountered the man on the bridge. During the incident, Taser was deployed.
“Investigators have secured police body-worn video footage and initial accounts have been obtained from the officers involved. The Taser used has also been gathered and will be analysed. Investigators have overseen forensic examination of the scene.”
The Metropolitan Police said on Saturday that officers challenged the man before the taser was discharged, but this “did not enable the officers to safely detain him” and he “subsequently entered the river”.
A rescue operation was launched and the man was pulled to safety by the Royal National Lifeboat Institution.
The man’s family will be supported by specialist officers and the Met’s Directorate of Professional Standards will investigate, the force said.
Detective Chief Inspector Rory Wilkinson of the Met’s Central West BCU said on Saturday: “I understand that there are always concerns about incidents in which people come to harm having been in contact with police.
“All Met officers know that they are accountable for their actions, and a full investigation is under way to establish exactly what happened.”
