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.
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.
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.
