SINGAPORE - A 41-year-old man was charged in court on Wednesday (Oct 7) morning with the murder of his five-year-old son.

Philippe Marcel Guy Graffart is accused of killing his son, Keryan Gabriel Cedric Graffart, in their home sometime between 8.54pm on Monday and 5.29am on Tuesday.

No plea was taken.

The case will be heard in court again on Oct 28.

Earlier on Wednesday, Graffart arrived in the State Courts in an unmarked police car just before 8.50am.

Dressed in a black T-shirt and blue shorts, and escorted by police officers in the car, he looked dazed and tired.

The Belgian national was found with self-inflicted injuries outside Bukit Timah Neighbourhood Police Centre just past 5am on Tuesday.

An hour later, police found his son, Keryan, dead in their 32nd-storey apartment in D'Leedon condominium located 2km away in Farrer Road.

Keryan is understood to have been strangled. Hand-shaped bruises were supposedly found all over his neck.

Graffart was arrested for murder.

He is the head of the Singapore investment management arm of Nordea, a company that describes itself as the largest financial group in northern Europe.

It is believed that he had been fighting for custody of the boy with his former wife.

The Belgian Embassy, when contacted on Tuesday, declined to comment on the case.

Graffart's Facebook page showed a father and son who shared a loving relationship.

A post dated Aug 24 showed him taking his child to a fire station. He had posted then: "It is so good to finally see you, my son."

A few days later, he put up a picture showing him embracing Keryan at the Canadian International School. The boy, dressed in his school uniform, was pictured beaming widely.

He wrote: "I am very proud of you Keryan, you are a big boy now."

Another photograph and a video taken by Graffart show the boy celebrating his fifth birthday two weeks ago, playing with balloons and blowing out candles on his birthday cake.

District Judge Eddy Tham granted the prosecution's application to remand Graffart for psychiatric observation at the medical complex in Changi Prison.
