KUALA LUMPUR (AFP) - Malaysian government scientists were on Friday (Feb 17) examining samples from the autopsy of the half-brother of North Korea's leader, after the 45-year-old was assassinated at Kuala Lumpur's airport.
Police were meanwhile questioning two female suspects who were arrested carrying Vietnamese and Indonesian passports, as well as a Malaysian man, as they attempted to shed light on the murder of Mr Kim Jong Nam.
Lab forensics received samples from the post-mortem on late Thursday and will "conduct the analysis as soon as possible", Dr Cornelia Charito Siricord from the science ministry's chemistry department told national news agency Bernama.
The estranged older half-brother of Mr Kim Jong Un had some kind of liquid sprayed on his face after being set upon by two women as he readied to board a flight to Macau on Monday, Malaysian police said.
He told airport staff that he was suffering from a headache and was taken to the airport clinic grimacing in pain, according to Malaysian media citing CCTV footage from the airport.
He was rushed to hospital suffering from a seizure but was dead before he arrived.
South Korea has pointed the finger of blame at the North, citing a "standing order" from Mr Kim Jong Un to kill his sibling and a failed assassination bid in 2012 after he criticised the regime.
Pyongyang has made no comment on the killing, but its diplomats objected to the post-mortem being carried out, a senior Malaysian official familiar with the investigation told AFP.
Malaysia's Deputy Prime Minister Ahmad Zahid Hamidi said on Thursday that he believed North Korea had put in a request to claim the body through the police and the hospital, and that Malaysia was ready to comply once investigations were completed.
Police on Wednesday arrested a 28-year-old woman carrying a Vietnamese passport which identified her as Doan Thi Huong. She was shown in CCTV images from the airport wearing a white top with the letters "LOL" emblazoned on the front, according to Malaysian media.
Officers later arrested Mr Muhammad Farid Bin Jalaluddin, a 26-year-old Malaysian man. He led them to his girlfriend, a 25-year-old Indonesian named Siti Aishah who was also arrested.
Police obtained a seven-day remand order for the two female suspects, Selangor state police chief Abdul Samah Mat told AFP.
