The police have scrutinised several closed circuit television (CCTV) recordings at the Kuala Lumpur 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 Tan Sri Khalid Abu Bakar, when contacted by Bernama, 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.-- Bernama
