A body has been recovered from the River Thames near Kingston.
A search was launched after a 47-year-old reportedly entered the water from the riverside near Kingston High Street and began swimming on Monday evening, but did not resurface.
A body, believed to be the same man, was recovered at around 4.30pm on Wednesday.
His next-of-kin have been informed and the death is not being treated as suspicious.
Inspector Stuart Simpson, from the Metropolitan Police's Marine Policing Unit, said: "Whilst at times, the Thames may look appealing, especially in this hot weather, it remains very dangerous all year round.
"On initial entry, the water can seem warm on the surface, but further in it can be freezing cold and there are often very strong undercurrents.
"The initial shock of the cold water is often what leads to people going subsurface and subsequently drowning."
