Malaysian police have arrested a third person in connection to the murder of North Korean leader Kim Jong Un’s half-brother.
An Indonesian woman and a Malaysian man, believed to be the woman’s boyfriend, were detained on Thursday night local time, after a woman was arrested on Wednesday.
South Korean intelligence chiefs say Kim Jong-Nam was poisoned as he walked through Kuala Lumpur International Airport on his way to board a flight for Macau.
The 45-year-old had some kind of liquid sprayed in his face after being set upon by two women, Malaysian police have said.
He was rushed to hospital suffering from a seizure, but was dead before he got there.
A 28-year-old woman, was arrested at Kuala Lumpur International Airport after the assassination, and was carrying a Vietnamese passport with the name Doan Thi Huong.
Fairfax Media has quoted Malaysian Police Inspector-General Khalid Abu Bakar said the second woman was carrying an Indonesian passport under the name of Siti Aishah, which said she was born in Serang.
"She was identified based on CCTV footage at the airport and was alone at the time of arrest," Mr Khalid told Fairfax Media.
CCTV images that emerged in Malaysian media, purportedly of one of the suspects, showed an Asian woman wearing a white top with the letters "LOL" emblazoned on the front.
North Korea 'objects to autopsy'
Kim's body was being held at Kuala Lumpur Hospital following an autopsy, the results of which have not yet been released.
North Korea had objected to the post-mortem examination being carried out, a senior Malaysian official familiar with the investigation told AFP.
"But we told them to follow Malaysia's laws," he added.
An official at the morgue said they had no indication who would claim the body or when.
But North Korean embassy officials were seen visiting the hospital's forensics department in a diplomatic vehicle on Wednesday afternoon and again overnight.
If confirmed, the assassination, which analysts said could have been ordered over reports Kim was readying to defect, would be the highest-profile death under the watch of the North's young leader Kim Jong-Un.
Jong-Nam was the eldest son of Kim Jong-Il, but on his father's death in 2011 the succession went to Jong-Un, who was born to the former leader's third wife.
The first-born had at one time been set to assume the leadership of his isolated country, but fell out of favour after an embarrassing attempt to get into Japan on a fake passport in 2001.
He has since lived in exile, with much of his time spent in the gambling enclave of Macau, where he was believed to have enjoyed some protection from Chinese security forces.
Known as an advocate of reform in the North and believed to have ties with Beijing's elite, Jong-Nam once told Japanese reporters that he opposed his country's dynastic system.
Reports of purges and executions have emerged from Jong-Un's North Korea in recent years, as the young leader tries to strengthen his grip on power in the face of international pressure over his country's nuclear and missile programs.
In 2012 Jong-Nam sent a letter to his younger brother begging him to spare his life, a member of South Korea's parliamentary intelligence committee told reporters after news of the airport killing broke.
