Inspector-General of Police Tan Sri Khalid Abu Bakar has dismissed North Korea's allegation that Malaysia was purposely delaying the process to release and send home Kim Jong Nam's remains.

He said as long as DNA from Jong Nam's family had not been obtained, the investigation on the case could not be completed.

North Korea, he stressed, must abide by the provisions of the law set by Malaysia, and should seek advice from their lawyers if it disagreed with the action by police.

"Their lawyers can advise them. We have rules in Malaysia. While in Malaysia, everyone has to obey and follow our rules and regulations...that includes North Korea," he told Bernama this morning.

Khalid was commenting on North Korean ambassador to Malaysia Kang Chol's statement yesterday accusing Malaysia of purposely rejecting their claim for the remains of Jong-nam, the half-brother of North Korean leader Kim Jong-un.

Kang Chol made the statement to the media in the compound of the National Institute of Forensic Medicine, Kuala Lumpur Hospital, about 11.45pm last night.

Yesterday, Selangor Police chief Datuk Seri Abdul Samah Mat said priority to claim the body was accorded to close family members to facilitate identification.

However, to date, only the North Korean embassy here had come forward to claim the remains.

On Monday, Jong-nam whose name was stated as Kim Chol in his passport was reported to have died on the way to hospital after complaining about feeling unwell at Kuala Lumpur International Airport 2. --Bernama
