A second man has died in less than 24 hours on the Canary Wharf estate, after “falling from height” in a shopping centre in the east London financial district, according to police.

Metropolitan police officers, the London ambulance service and London’s air ambulance were called to Cabot Place shopping centre where the man, believed to be in his 50s, was pronounced dead at the scene just after 9am.

The area remained cordoned off on Tuesday morning, as passing commuters circulated photos of emergency services at the scene and witness accounts on social media.

Canary Wharf Group, the area’s owner, tweeted: “We can confirm that there has been a medical incident on the Canary Wharf estate. We are supporting the emergency services in their response.”

The victim’s next of kin have not yet been informed and inquiries continue, police said.

His death came less than a day after a man died on Monday afternoon when he fell from an escalator at Canary Wharf underground station.
