Police are mulling action over the leak of a CCTV recording connected to the death of Kim Jong Nam, the elder brother of North Korea's leader, Kim Jong Un.

The dissemination of the CCTV recording is seen as interfering in police investigation into the case.

Inspector-General of Police Tan Sri Khalid Ibrahim, when contacted by Bernama on the matter and the action to be taken against those who spread the recording, replied succinctly: "We will study."

Meanwhile, Selangor police chief Datuk Seri Abdul Samah Mat, when posed the same question, said police would investigate the matter before taking further action.

"This matter (dissemination of the CCTV recording) to some extent disturbs the task of the police," he said when contacted by Bernama.

The clip lasting 2.33 seconds, which was aired by a foreign broadcasting company, went viral on social sites since last night.

Last Sunday, Jong-nam was reported to be at klia2 to board a flight to Macau, when suddenly a woman covered his face with a piece of cloth believed to have been laced with liquid poison.

Jong-nam, whose name was stated as Kim Chol on his passport, died while being rushed to the Putrajaya Hospital. -- BERNAMA
