A senior Hong Kong police officer has died while swimming in the Hudson River as part of the Ironman US Championship in New York.
Reports said superintendent Andy Naylor, 43, of the Criminal Intelligence Bureau had a medical problem during the swimming part of the grueling triathlon.
The veteran competitor "experienced distress" during the 3.9-kilometer swim in the Hudson at the start of the all-day competition, a publicist for the race organizers said. The course runs along the New Jersey shoreline, just north of the George Washington Bridge.
Naylor was pulled out of the water and taken to a hospital at Englewood Cliffs, New Jersey, but did not survive.
The organizers said the cause of death is unknown. An autopsy is planned.
Contestants in the race followed their swim in the Hudson with a 180-kilometer bicycle ride through the suburbs, and then a 42.2km marathon that finished at Manhattan's Riverside Park.
Jordan Rapp, a winner of multiple Ironman titles, won the race in an unofficial time of eight hours, 11 minutes and 18 seconds.
Naylor was on holiday when he took part in the event. He used to work in the force's Special Duties Unit and the Police Tactical Unit.
He has taken part in many police and open sports competitions and has won many awards, including the Dowman Road Race in 2007.
He finished the 11.4km race in just 36 minutes and 37 seconds, setting a record. The race is an event open to police officers in Hong Kong.
A police spokesman said the force is sorry to hear about Naylor's death. He said the force has been in contact with Naylor's family and offered assistance.
