KUALA LAMPUR: 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 Korean leader KimJongUn. According to a police statement “The man was carrying Malaysian documentation issued to foreign workers, which identified him as 46-year-old North Korean citizen RiJong Chol, when he was arrested on Friday evening”. He is the first North Korean to be arrested in connection with the case, after detectives detained an Indonesian woman named Siti Aishah (25) and her Malaysian boyfriend, along with a woman carrying a Vietnamese passport which identified her as DoanThi Huong (28) North Korean state media has remained silent on the murder of KimJong Nam at Kuala Lumpur airport on Monday, which Seoul has blamed on poison-wielding female agents working for Pyongyang.
