The man suffered a serious head injury after a sofa fell from one of the privately-rented properties in London’s five star W Hotel in Leicester Square.
A passer-by, who witnessed the man’s injuries, told the Sun:
"The sofa came flying over the top of the hotel’s flat roof. I can’t understand how something that big and heavy came to fall over the edge."
