Police are looking for the second secretary to the North Korea Embassy in Malaysia and another person facilitate their investigation into the death of Kim Jong-nam.
The other individual is an employee of the North Korean airline, Air Koryo.
Inspector-General of Police Khalid Abu Bakar said police had requested the embassy to hand over the individuals to assist investigation.
“We submitted the request today and if they refused to hand over, warrants of arrest will be issued on both of them,” he told a press conference at the federal police headquarters in Bukit Aman in Kuala Lumpur today.
Police believe the second secretary, Hyon Kwang-song, 44, and the airline employee, Kim Uk-il, 37, were still in the country.
When asked about the other four suspects who were believed to have returned to Pyongyang, Khalid said police had asked North Korean government to assist in apprehending them.
“We believe these four are heavily involved in the attack,” he said, adding that police are hoping for cooperation from the North Korean government.
On another note, Khalid said police investigation revealed that the two women detained in connection with Jong-nam’s death, knew the substance they used in the attack was toxic.
Khalid said Doan Thi Huong and Siti Aisyah were instructed to wash their hands after the attack on Feb 13.
“We are ruling out the possibility that the women thought the attack was a prank or a shooting for a television show.
“We expect their remand to be extended today for seven more days,” he said.
