The top leader of the Democratic People’s Republic of Korea (DPRK), a senior Malaysian police official said on Thursday.
Abdul Mat, the police chief of Selangor state, told newsmen that the suspect, a 26-year-old male Malaysian, was arrested in Ampang city of the state of Selangor.
According to the police, the man is believed to be the boyfriend of the second suspect, a bearer of an Indonesian passport who was arrested.
The police have been looking into the connections between the suspects and trying to pin down their roles in the death of Kim Jong Nam.
The police have been investigating as a murder case instead of sudden death of Kim and a local court has granted a seven-day remand order for the first two suspects.
The first female suspect, holding a Vietnamese passport, was arrested on Wednesday at the Kuala Lumpur International Airport’s second terminal, where the deceased Kim looked for help after feeling unwell on Monday.
Kim died later on Monday en route to hospital.
His body was taken to a hospital in Kuala Lumpur on Wednesday for post mortem to ascertain the cause of his death.
Report says the results of the post Morten are yet to be released.
