Two women have told police that they were duped into what they believed was a harmless prank
Malaysian police have re-enacted the killing of Kim Jong-Nam - the half-brother of North Korea's leader Kim Jong-Un - at Sepang airport.
The 45-year-old is believed to have been killed by two female Pyongyang agents at Kuala Lumpur International Airport on Monday as he waited to catch a flight to Macau.
Two women and one man have so far been arrested in connection with the murder.
The women are believed to have used poisoned needles, a poisoned spray or a poison-laced cloth.
Meanwhile, one of the women - captured on CCTV wearing a jumper with 'LOL' written on the front - reportedly cut her own hair the day before the attack.
According to a hotel receptionist, the 28-year-old woman, who had checked in under the Vietnamese name of Doan Thi Huong, was also in possession of wads of cash.
The second woman, 25-year-old Siti Aishah, is reported to be of Indonesian origin and had come to Malaysia to find work.
Both women have told Malaysian police that they were duped into what they believed was a harmless prank.
The arrested man, 26-year-old Muhammad Farid Bin Jalaluddin, is the Malaysian boyfriend of Ms Aishah.
Meanwhile, Malaysia has told Pyongyang that Kim Jong-Nam's body will not be released until his family provide DNA samples.
North Korea, who objected to a post-mortem examination, have submitted a request to reclaim the body.
State police say they are still looking for several more suspects.
