A British man is under guard in hospital after he fell from a hotel balcony in Greece with his two children, killing one of them.
Mr Hogan is being treated for arm, leg and chest injuries
Liam Hogan, six, died in the 50ft fall from the fourth-floor balcony with his father John, 32, in Crete, on Tuesday.
Two-year-old daughter Mia survived the fall and has been released from hospital with a broken arm.
Mr Hogan, from near Bristol, was reported to have suffered chest, arm and leg injuries.
Panayiotis Sparakis, director of Agios Nikolaos hospital where the family were initially treated, said it was a "truly tragic" case.
Mr Hogan's wife, Natasha Hogan, works as a nurse in the accident and emergency department at the Royal Gwent Hospital in Newport, south Wales.
The family, who live in Bradley Stoke, were said to have travelled for a two-week holiday and were staying at the four-star Petra Mare Hotel in Ierapetra, in Crete, on the south coast of the island.
A Foreign Office spokeswoman confirmed on Thursday Mr Hogan had undergone surgery following the fall, but had not yet been charged with any offence.
She added: "Mr Hogan went in for surgery today but he is not likely to be charged until he recovers from that."
She added Mr Hogan, who runs a tiling business, was under police guard at the University General Hospital in Heraklion, Crete.
