Malaysia Police Arrest N Korean Man Over Kim Murder 

Kuala Lumpur: Malaysian police said on Saturday they had arrested a North Korean man, the fourth person to be detained in connection with the murder of the half brother of the North's leader.

The man was carrying Malaysian documentation issued to foreign workers, which identified him as 46-year-old North Korean citizen Ri Jong Chol, when he was arrested on Friday evening, according to a police statement.

He is the first North Korean to be arrested in connection with the case, after detectives detained a 25-year-old Indonesian woman named Siti Aishah and her Malaysian boyfriend, along with a woman carrying a Vietnamese passport identifying her as Doan Thi Huong, 28.

North Korean state media has remained silent on the murder of Kim-Jong Nam at Kuala Lumpur airport on Monday, which Seoul has blamed on poison-wielding female agents working for Pyongyang.

'Malaysia acting with hostile forces in Kim investigation'

Meanwhile Pyongyang has accused Malaysia of colluding with "hostile forces", saying it would reject any results of a post-mortem examination carried out by Kuala Lumpur on the body of Kim Jong-Nam, the half brother of North Korea's leader.

The comments from the North Korean ambassador were the first official remarks from the country since the assassination of Kim Jong-Un's estranged older sibling at Kuala Lumpur international airport on Monday.

But ambassador Kang Chol stopped short of identifying Jong-Nam and did not comment on the cause of death, while North Korean state media has remained silent on the killing.
