Malaysian authorities investigating the murder of North Korean leader Kim Jong-un’s half-brother have tightened border control as part of their efforts to track down key suspects.
According to local media on Thursday, Malaysian authorities beefed up security at all immigration points shortly after the assassination of Kim Jong-nam.
Police chief Abdul Samah Mat said the measures include tightening monitoring efforts at the Kuala Lumpur International Airport and at all of the airport’s exit and entry areas.
The police chief told the Bernama state news agency that the latest move is aimed at stopping four key suspects from sneaking out of Malaysia.
Local police caught the first of the six suspects, a woman on Wednesday, two days after Kim’s murder. Another female suspect was arrested the next day.
But police have yet to confirm the whereabouts of the four remaining suspects, who are said to be men of North Korean nationality.
Kim Jong-nam was killed on Monday at Kuala Lumpur International Airport after coming in contact with two women. He died before arriving at the nearby Putrajaya Hospital.
