Bernama news agency reported that she has been remanded in custody for seven days along with a woman who was caught at Kuala Lumpur International Airport on Wednesday, two days after Kim Jong Nam was assaulted there with what was believed to be a fast acting poison.
Police said the latest arrest was made at 2 a.m on Thursday, and the woman was carrying an Indonesian passport, unlike the first suspect who held Vietnamese travel papers.
The woman arrested in the early hours of Thursday was alone when she was apprehended, a police statement said. Her Indonesian passport bore the name Siti Aishah, and gave her date of birth as February 11, 1992, and place of birth as Serang, Indonesia. The statement gave no other details.
Lawmakers in South Korea earlier cited their spy agency as saying it suspected two female North Korean agents had murdered Kim Jong Nam. U.S. government sources also said they believed North Korean assassins were responsible.
