KUALA LUMPUR, Feb. 18 (Xinhua) -- Malaysian police on Saturday dismissed allegation by ambassador of the Democratic People's Republic of Korea(DPRK) that Malaysia had purposely delayed the release of the body of its citizen.

Malaysian police chief Khalid Abu Bakar told state news agency Bernama that the investigation could not be completed as long as the DNA sample from the family had not been obtained.

"We have rules in Malaysia. While in Malaysia, everyone has to obey and follow our rules and regulations," Khalid was quoted as saying.

DPRK's ambassador Kang Chol told media late Friday that the Malaysian side had forced the post mortem without their permission and witnessing, and his country would categorically reject the result of the "unilaterally conducted" post mortem.

The victim, whom the Malaysian authorities claimed as Kim Jong Nam, the half brother of DPRK's top leader, died in Kuala Lumpur on Monday.
