The police have scrutinised several closed circuit television (CCTV) recordings at the KL International Airport 2 (KLIA2) in the investigation over the killing of Kim Jong-nam, elder half-brother of North Korean leader Kim Jong-un.

Inspector-general of police Khalid Abu Bakar, when contacted by Bernama yesterday, said the police had also taken the statements of several witnesses at KLIA2.

"Done," he said in brief to a question if the police had done so.

To date, a local man and two foreign women were detained to help in investigations over the killing of Jong-nam.

On Monday, Jong-nam was reported to be in KLIA2 to board a flight to Macau when a woman was believed to have put a cloth containing liquid poison over his head.

Jong-nam was reported to have died on the way to the hospital.
