KUALA LUMPUR: The second secretary at the North Korean Embassy here is among two individuals being sought by police to facilitate the probe into the assassination of Kim Jong-Nam. Inspector-general of Police (IGP), Tan Sri Khalid Abu Bakar today revealed that police had identified the two other Korean men who were earlier reported to be in the country. He said the first was identified as Hyong Kwang Song, 44, second secretary of the North Korean Embassy here while the other is Kim Uk Il, 37, who is a staff of Air Koryo, the state-owned national flag carrier airline of North Korea. "We have called the North Korean Embassy yesterday (Tuesday) to interview the two men and hope the embassy will give us their co-operation. "However, if they do not come forward, we will compel them to do so by issuing an arrest warrant," he said. In a packed press conference attended by almost 100 local and foreign media personnel at the federal police headquarters, Khalid said police are also tracking down another suspect, Ri Ji U, 30, known as "James". On the other four suspects who have gone back to Pyongyang, North Korea, Khalid said police have asked North Korean government to assist in apprehending them. Khalid further revealed that the two women, Vietnamese Doan Thi Huong, 28, and Indonesian, Siti Aishah, 25, had applied poison on their palms and wiped it on Jong-Nam's face. "They knew it was toxic and well aware of what they were doing. You can see from the CCTV footage that one of the suspects walked with her hands extended to the bathroom to wash off the substance," he said adding that police believe the four men supplied the liquid to the female suspects. He added the two female suspects were trained "a few times" at areas such as KLCC and Pavilion, on how to carry out the assassination. Khalid also rejected North Korea's request for them to work together on the investigations. "It is not under their jurisdiction, it is under ours," he said. He also denied that Jong-Nam's son, Kim Han Sol had arrived in Malaysia and said they were all merely just "rumours". He said no family members have come forward to identify or provide DNA samples for them to positively identify the victim as Kim Jong-Nam. He said police will refer to the victim as Kim Chol, until they can positively identify him. Jong-Nam, the half-brother of North Korean leader Kim Jong-Un, was killed on Feb 13 by two women who splashed chemicals on his face at the Kuala Lumpur International Airport 2 (klia2) departure hall. He was about to leave for Macau. Meanwhile, on an unrelated matter, Khalid said police have formed a task force headed by Selangor CID chief SAC Fadzil Ahmat to search for abducted pastor Raymond Koh Keng Joo. He said police have so far recorded statements from eight people in the course of the investigations. Koh was abducted last Monday by a group of masked men on Jalan SS4B/10, Petaling Jaya, less than 100m from the police housing complex. He was driving a silver car bearing the licence plate ST 5515 D. The family is offering a reward of RM100,000 for information on his whereabouts. He also said police have started an investigation for wrongful confinement of persons against the investigating officer who failed to follow a court order to release S. Balamurugan, 44, who died at the North Klang police headquarters on Feb 7. Earlier, he was taken to a magistrate's court to be remanded, which was denied after the magistrate saw him vomit blood. The court ordered Balamurugan to be taken to a hospital or released but police took him to the police headquarters where he died.
