Officials in Malaysia said early Wednesday they have arrested a female suspect in the death of Kim Jong Nam, the estranged brother of North Korean leader Kim Jong Un. Kim was allegedly poisoned Monday at Kuala Lumpur’s international airport, and local reports said the women involved in Kim’s death were believed to be North Korean operatives who fled in a taxi. Malaysian police said the apprehended suspect was identified from CCTV footage at the airport and was taken into custody Wednesday when she returned to the airport. Police identified her as a 28-year-old woman named Doan Thi Huong. She was carrying a Vietnamese passport. Authorities are still looking for other suspects related to the case.
