The reports described the mystery man as a "middle-aged Korean American".
As the criminal trial for who killed North Korean leader Kim Jong-un's half brother, Kim Jong Nam, is set to resume, more details have emerged about what happened in the lead up to his shocking death, news.com.au reports.
Jong Nam returned from Langkawi to Kuala Lumpur on the evening of 12 February. He died in agony within minutes, and the women were arrested days later. Lawyers for the two women said they believed they were taking part in a reality television show hoax.
Photos emerged of Nam shortly after the murder showing him slumped in a chair at the airport.
Yesterday, a witness told the court that Jong-nam had met with an unidentified American on the Malaysian resort island of Langkawi on February 9 a year ago, four days before his death.
On Jan 5, 2017, Siti Aisyah was approached at a nightclub by a Malaysian taxi driver, who asked her if she would participate in a Japanese video prank show, her lawyer, Gooi Soon Seng, told the court during his questioning of the lead police investigator in the case.
He added that Kim met with a USA national of South Korean origin at a hotel there the following day.
Fueling speculation that Kim had ties with US intelligence, Wan Azirul Nizam also confirmed that a forensic report on Kim's Dell laptop showed that some data was accessed by a USB pen drive several times on February 9, 2017, while he was in Langkawi.
In his cross examination, he grilled Azirul about Kim's Langkawi meeting with a Korean-American man based in Bangkok, which was first reported by Japan's Asahi Shimbun previous year. A day later he was dead, reportedly poisoned by a lethal nerve agent banned by the United Nations as a weapon of mass destruction, Daily Mail reports. He was allowed to leave Malaysia in March after a tense diplomatic stand-off between Malaysia and North Korea.
Siti Aisyah and Vietnamese Doan Thi Huong are the only suspects in custody.
Kim Jong Nam was the eldest son of North Korean leader Kim Jong Il.
Malaysian police previously said four North Korean suspects fled the country on the day that Jong-nam was attacked. The judge denied the request past year. Because North Korea is ruled by the Kim family dynasty, Kim Jong Un could theoretically be replaced with another Kim in a relatively bloodless coup. He was also caught trying to sneak into Japan to visit Disneyland Tokyo.
Four other North Koreans have been named as suspects, although the court has refused to release their identities.
Citing three sources, Nikkei Asian Review reported in August 2017 that top government officials in China and North Korea seriously considered a plot to remove Kim Jong Un in 2012, however the plot reportedly fell through and resulted in the dictator having his own uncle killed.
