Malaysian police seeking four more North Koreans in Kim Jong-Un's killing

Kuala Lumpur: Malaysian police said Sunday they were seeking four more North Korean suspects in the assassination of Kim Jong-Un`s half-brother, but the four had left the country on the day of the killing.

The suspects were all male and aged between 33 and 57, Deputy Inspector-General of Police Noor Rashid Ibrahim told a press conference. 

In addition to the four, three North Koreans were being sought to assist with enquiries, he said. 

Police on Saturday arrested a 46-year-old North Korean man called Ri Jong Chol, who was identified at the press conference as an IT worker living in Kuala Lumpur. 

Officers had already detained a woman carrying a Vietnamese passport as well as an Indonesian woman and a Malaysian man over the killing.

Kim Jong-Nam died Monday after an unidentified liquid was sprayed in his face at Kuala Lumpur International Airport, an attack which Seoul says was carried out by female agents on Pyongyang`s orders.

The North has demanded his body be returned but Malaysia has refused the request and said it must remain in the country until identified through a DNA sample from a family member. 

No family member has yet come forward, police said on Sunday.
