4:30 p.m.:

Malaysia's police chief says three North Koreans who had been sought in the killing of the North Korean leader's half brother were allowed to leave the country after investigators obtained their statements.

National police chief Khalid Abu Bakar told reporters Friday that "we have obtained whatever we wanted from them" and are "satisfied" with the North Koreans' statements. The three were believed to have been holed up in the North Korean Embassy.

Khalid says police are still seeking four other North Koreans who left Malaysia Feb. 13, the day Kim Jong Nam died after being poisoned in a Kuala Lumpur airport terminal. Two women accused of smearing Kim's face with poison are in custody.
