At least four North Korean suspects related to the death of Kim Jong-nam, the elder half-brother of the communist country's top leader Kim Jong-un, have fled Malaysia, police said on Sunday.
The cause of the death of Kim Jong-nam still remained unknown, Xinhua news agency quoted Deputy Inspector General of Police Noor Rashid Ibrahim as saying.
The 46-year-old was found dead on Monday at an airport here.
Ibrahim said they still need DNA samples from the next of kin of Kim to identify the dead man.
