KUALA LUMPUR, Feb. 16 (Xinhua) -- Malaysian police said Thursday a second female suspect, who bears an Indonesian passport, has been arrested early in the morning in connection with the death of a man from the Democratic People's Republic of Korea (DPRK).

Malaysian police chief Khalid Abu Bakar said in a statement that the second suspect was also identified from a surveillance camera footage at the airport and was alone at the time of the arrest.

Based on the passport, the suspect is named "Siti Aishah" and was born on Feb. 11, 1992 in Serang of Indonesia.

Abdul Samah Mat, police chief of Selangor state, told Xinhua that the suspect was arrested in a hotel in Selangor near the capital of Kuala Lumpur.

Police are investigating as a murder case instead of sudden death of the man, and a local court has granted 7-day remand order for the two suspects.

The first female suspect holding a Vietnamese passport was arrested Wednesday at the Kuala Lumpur International Airport's second terminal, where the deceased DPRK man had looked for help for feeling unwell on Monday and died enroute to the hospital.

Malaysian police said earlier that the 46-year-old man was holding a DPRK passport under the name Kim Chol. His body was taken to a hospital in Kuala Lumpur Wednesday for postmortem to ascertain the cause of his death.

The results of the postmortem are yet to be released.
