Malaysian Police has detained a woman in connection with the murder of Kim Jong Nam, estranged half brother of North Korean leader Kim Jong Un. Police say the woman was holding Vietnam travel papers adding that other suspects in connection with the murder were still at large.

The detained woman was identified from a CCTV footage at the airport and was apprehended with documents in the name of Doan Thi Huong. “Police are looking for a few others, all foreigners,” Deputy Inspector-General Noor Rashid Ibrahim told Reuters.

The gender or nationalities of the other suspects were however not revealed. South Korean sources from its spy agency say that they suspected spies from North Korea to be responsible for the murder. The spy agency told them that the young and unpredictable North Korean leader had issued a “standing order” for his half-brother’s assassination, and that there had been a failed attempt in 2012. “The cause of death is strongly suspected to be a poisoning attack,” said South Korean lawmaker Kim Byung-kee, who was briefed by the spy agency.

US government sources also held the similar view that North Korean assassins were responsible for the murder. Kim had been at the airport’s budget terminal to catch a flight to Macau on Monday when someone grabbed or held his face from behind, after which he felt dizzy and sought help at an information desk, Malaysian police official Fadzil Ahmat said. Recall that Kim Jong Nam, brother of North Korea Leader, Kim Jong Un, was killed on Tuesday in Malaysia, a South Korean government source said. Kim Jong Nam, the older half brother of the North Korean leader, who is believed to be in his mid-40s has spent most of his time outside North Korea. He had spoken out publicly against the reign of his family in the country.

Police in Malaysia told Reuters on Tuesday an unidentified North Korean man had died en route to hospital from Kuala Lumpur airport on Monday.
