KUALA LUMPUR (Reuters) - The half-brother of North Korean leader Kim Jong Un was carrying $100,000 in cash in his backpack at the time of his murder, the police officer investigating the case told a Malaysian court on Wednesday.

Indonesian Siti Aisyah, 25, and Doan Thi Huong, 28, a Vietnamese, are charged with murdering Kim Jong Nam by smearing his face with VX, a chemical poison banned by the United Nations, at Kuala Lumpur airport on Feb. 13.

The money is now stored in a safe in the office of the police chief of the Sepang district, which has jurisdiction over the murder site, police official Wan Azirul Nizam Che Wan Aziz said.

Wan Azirul said he took posession of the victim’s blazer, backpack and watch and handed them to the chemistry department for analysis, but was later told by investigation authorities to hand them over to representatives of the North Korean embassy.

“I do not know why, I was following orders,” he added.

In court, the prosecution played more than 30 videos of closed-circuit television footage of the women’s activities, after Judge Azmi Ariffin overruled defense objections to their admissibility, saying it could be challenged later in the case.

The defense lawyers for both Huong and Siti Aisyah said the videos could be considered hearsay, as the investigating officer did not record them himself and was not present to witness the crime.

Some of the footage, dated Feb. 11, appeared to show Huong approaching an unidentified man from behind and placing her hands around his neck and face, before backing away slowly with her head slightly lowered and her hands put together.

Most of the videos, however, appeared to show Huong and Siti Aisyah before, during and after the attack on Kim Jong Nam. The two women were mostly seen in separate locations, save for during the attack and when they were at a taxi-stand later.

The two women were in the same area at the time of the attack, Wan Azirul, who is with the Sepang criminal investigations department, confirmed.

The hearing resumes on Thursday, with Wan Azirul returning to the witness stand.
