A passer-by has died after a sign fell from a William Hill betting shop in Camden, North London.
The man, who has not yet been named, is believed to have been in his 20s or 30s.
He was treated at the scene on Camden Road, NW5, on Monday afternoon, before being taken to University College Hospital, where he died.
A nearby ambulance crew and a single responder arrived on the scene just before 4.55pm.
A London Ambulance Service spokeswoman said: “Extensive efforts were made to resuscitate the patient both at the scene and on the way to hospital.”
“He was taken to UCH as a priority on blue lights.”
A spokesman for the Metropolitan Police said last night: “At this early stage it appears the man received his injuries after being struck by sign or board which has fallen from a building.”
“Officers from Camden are on scene.”
A spokeswoman for William Hill said: “Following the tragic events in Camden on Monday evening, William Hill is extending full co-operation to the authorities as they seek to understand the circumstances leading to this deeply regrettable and unforeseen accident.
“We would like to express our sincere condolences and sympathy to the family for their loss.”
