One of France's most popular reality TV shows has been hit by a second tragedy when a doctor committed suicide just days after treating a contestant who died of a heart attack.
The show, called Koh Lanta, is based on the American series Survivor in which contestants compete in challenges to earn food rations in an exotic wilderness.
Dr Thierry Costa, a well-known TV doctor in France, committed suicide on Monday following the fatal heart attack of a 25-year-old contestant.
In a suicide note released by the show's production company, Dr Costa says his name was "smeared" in the press and speaks of his fear of returning to France to fight for his reputation.
The first hint of trouble came last week when contestant Gerald Babin complaining of cramps in his arms while filming on the tropical island of Koh Rong in Cambodia.
He had reportedly been taking part in a tug-of-war challenge, although the production company Adventure Line Productions has not confirmed this.
Dr Costa was called to examine Mr Babin before deciding he should be airlifted to a local hospital, but he died after suffering a heat attack in the helicopter.
Cambodian authorities determined that he died of natural causes, but news agency AFP reports that French authorities opened a preliminary enquiry into "involuntary homicide".
Adventure Line Productions released a suicide note from Dr Costa in which he blames "unfair accusations" in the press for his death. A translated extract on The Times (£) reads:
He goes on to request that his body be cremated in Cambodia instead of being repatriated to France.
The French broadcaster TF1 has cancelled the current series, which would have its sixteenth, in light of the tragedies.
