A body was discovered in one of Britain's most visited lakes today.
Police divers dragged a man from the Serpentine in London's Hyde Park at lunchtime after a walker spotted the corpse in the water.
Detectives say the death is being treated as "unexplained".
Visitors enjoying park strolls on the warmest day of the year so far were told to move away as police put a cordon up around the immediate area.
A Scotland Yard spokesman said: "We were called at around 11.50 today to the Serpentine to reports that a body had been seen.
"Marine support teams recovered a man's body."
The Serpentine will be the centrepiece for the London 2012 Olympics triathlon and 10km marathon swimming event.
