He had been left in a critical condition after a cardiac arrest following the crash.

The collision happened as he was returning to the Athletes' Village in a taxi in the early hours of Friday morning.

Germany will commemorate Henze's death in the Olympic Village on Tuesday, and the country's flag will be flown at half-staff at all Olympic sites in Rio.

The Olympic body 'is mourning the loss of a true Olympian,' IOC President Thomas Bach said.

'Our sympathy is with the family of Stefan Henze, his friends and all of the German Olympic team.'

Henze, who won an Olympic canoeing silver medal in the 2004 Athens Olympics, is believed to have been returning from a night out with colleague Cristian Katini, sport scientist for the German canoe team, when the crash happened around 4.50 am.

In a statement, the taxi driver Artur de Almeida Campos, 26, claimed Katini had suddenly grabbed the wheel as he took a fork in the road on the main Avenida das Americas expressway and the car smashed head-on with a concrete barrier.

Katini and the taxi driver escaped with cuts and bruises, but Henze, who wasn't wearing a seat belt, hit his head in the collision and was 'seriously injured', according to a statement from the German Olympic contingent.

Both Germans were taken to the nearby Lourenco Jorge hospital, and Henzewas later transferred to the specialist Miguel Couto hospital in the Leblon district, where he underwent emergency surgery around 10 am.

Sources at the hospital said he suffered a heart attack as medics battled to save his life, but was resuscitated.

Members of the German Olympic delegation were later seen outside the Miguel Couto hospital after visiting Henze following his surgery.

He was then under observation in the hospital's intensive care ward, but still in a 'critical condition', according to the hospital at the time.

In an interview before the Rio Games, Henze said he hoped to make his Olympic comeback in Brazil, this time as a coach.
