A second woman has been arrested in the connection with the death of Kim Jong-nam, the brother of North Korean leader Kim Jong-un.
Mr Kim died on Monday after apparently being poisoned while waiting to board a flight in Kuala Lumpur, Malaysia.
Police say they have now finished their post-mortem examination of his body, though the results have not yet been made public.
One woman, travelling on a Vietnamese passport, is due to appear in court.
The inspector general of the Royal Malaysia police, Sri Khalid Bin Abu Bakar, said the second woman was detained on Thursday over the death of “a Korean male”.
She was identified from airport CCTV footage and had an Indonesian passport.
Malaysia has yet to formally confirm that the dead man, who was travelling under the name Kim Chol, is Kim Jong-nam, but South Korea says it is certain.
There is widespread speculation that North Korea was behind the killing, but there has been no confirmation.
North Korea is on Thursday celebrating what would have been the 75th birthday of Kim Jong-il, the late leader and father of both Kim Jong-nam and Kim Jong-un.
Kim Jong-un was seen attending a ruling party meeting on Wednesday. Footage aired on state media showed him grim-faced, reported South Korea’s Yonhap news agency, and he did not wave when he left, as is customary.
No request from North Korea
Selangor Police Chief Abdul Samah Mat told the BBC the examination of Mr Kim’s body was completed on Wednesday evening, but there has been no indication of whether the results will be made public.
Reports on Wednesday said North Korea had asked to claim the body, but Mr Samah said that while officials from the embassy did visit the hospital they had not officially asked to remove the body.
He said Malaysia had no objection in principle to releasing the body to North Korea, if such a request were made.
Woman due in court
Mr Kim is believed to have been attacked by two women, using some form of chemical.
A grainy image taken from security camera footage in the airport, which has been broadcast in South Korea and Malaysia, shows a woman wearing a white T-shirt with the letters “LOL” written on the front.
It is not clear whether either is the woman in the footage, and police say they are still looking for “a few” other suspects.
A murder mystery: Karishma Vaswani, BBC News, Kuala Lumpur
An alleged assassination attempt, a grainy shot of a woman wearing a T-shirt with “LOL” written on it, and a dead body that has yet to yield any information.
It has all the makings of a murder mystery, with more questions than answers.
Who is the Vietnamese woman the Malaysian police say they’ve arrested, and what does she have to do with the case?
How is it possible that in a crowded airport, in broad daylight, a man can be accosted with some kind of toxic substance, and no trace of it is left behind at the crime scene?
People I spoke to at the airport who may have seen what happened were reluctant to talk about it, and at least two of them told me that they had been instructed not to talk by police.
Then there’s the investigation, which also appears to lack focus.
All Malaysian police officials will tell us is that once they have the results of the post-mortem they will be able to identify what really happened to the man believed to be Kim Jong-nam.
Kim Jong-nam was largely estranged from his family, after being bypassed for inheriting the leadership in favour of his youngest half-brother. He spent most of his time overseas in Macau, mainland China and Singapore.
He had spoken out in the past against his family’s dynastic control of North Korea and in a 2012 book was quoted as saying he believed his younger half-brother lacked leadership qualities.
But he had said he was not interested in assuming the leadership himself.
Unnamed US government sources have said they believe he was poisoned by North Korean agents.
South Korean spy chief Lee Byung-ho told South Korean MPs that Pyongyang had wanted to kill Kim Jong-nam for several years, but that he was being protected by China.
The secretive state has a long history of sending agents overseas to carry out assassinations, attacks and kidnappings.
But some analysts question what motive Kim Jong-un would have to kill his estranged half-brother, given the risk of the operation and possibilities for embarrassment, added to the fact that he was not seen as a threat to Mr Kim’s leadership.
Still, Mr Kim was reportedly targeted for assassination in the past. A North Korean spy jailed by South Korea in 2012 is said to have admitted trying to organise a hit-and-run accident targeting him.
