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.
