PETALING JAYA - Malaysian police will protect Mr Kim Han Sol, the son of assassinated North Korean Kim Jong Nam, should he turn up to identify his father's body at the Hospital Kuala Lumpur (HKL) mortuary, The Star reported.

Mr Kim Jong Nam is the estranged half-brother of North Korean leader Kim Jong Un. He was killed at Kuala Lumpur International Airport last week, with CCTV footage showing he was set upon by two foreign women, one of whom was said to have wiped his face with a cloth doused with a poisonous liquid.

Deputy Home Minister Datuk Nur Jazlan Mohamed said he was not aware if Mr Kim Han Sol was already in Malaysia but assured that the 22-year-old would be protected.

"All he has to do is to contact Wisma Putra or the other authorities if he intends to come to Malaysia. We will protect him as we don't want another death to happen here," Mr Nur Jazlan said.

There was a media frenzy at the KLIA2 arrival hall on Monday when word spread that Mr Kim Han Sol would arrive from Macau but the rumours turned out to be false.

A Special Task Force on Organised Crime team was deployed overnight at the mortuary because of the high-profile nature of the case.

On the fate of the four North Korean suspects who are believed to have fled the country following Mr Kim Jong Nam's assassination, Mr Nur Jazlan said it would depend on the identification of the victim and cause of death.

"If the death was under suspicious circumstances, the police can request for the four men to be extradited to assist in investigations," he said.

Mr Nur Jazlan said any request for the men to be extradited would need North Korea's cooperation.

"The question is whether North Korea will entertain us. What if they (North Korea) say they can't find the four, then what can we do?"

Police here have requested Interpol to help trace the four. Their photographs were also published.

Inspector-General of Police Tan Sri Khalid Abu Bakar said no family member has yet come forward to claim Mr Kim Jong Nam's body.

Khalid was refuting a report in a South Korean news portal Arirang that Mr Kim Han Sol had arrived at the HKL mortuary on Tuesday morning and claimed his father's body.
