SINGAPORE - Oscar-winning actress Nicole Kidman's father died in Singapore on Friday after suffering an apparent heart attack at The Tanglin Club where he had been staying.

Dr Antony Kidman, a renowned clinical psychologist, is believed to have collapsed when he was at the club's Wheelhouse restaurant, after completing his morning exercise. A doctor who was present tried to resuscitate the 75-year-old.

A spokesman for the Singapore Civil Defence Force confirmed that it received a call at about 8.10am on Friday requesting for medical assistance at 5 Stevens Road, where the club is located. When paramedics arrived shortly after, a few members of the public were already performing cardiopulmonary resuscitation on a Caucasian man in the restaurant, the spokesman added.

Paramedics carried on trying to resuscitate him on the way to Tan Tock Seng Hospital (TTSH). Police confirmed that he was pronounced dead at TTSH at 9.54am. They are investigating the unnatural death.

Dr Kidman was staying at The Tanglin Club as his son-in-law is a member there.

He had been visiting his younger daughter, Antonia, 44, who lives in Singapore with her banker husband and their six children.
