The whereabouts of former Phnom Penh police chief Heng Pov were still a mystery on

September 5 when Interior Ministry Spokesman Khieu Sopheak said he had "no official

word" on Pov's location.

Pov is believed to have been deported from Singapore - where he arrived on July 23

- to Malaysia.

Cambodian officials are trying to have Pov extradited to Cambodia to face various

charges including assassination, attempted assassination, and kidnap.

While overseas, Pov has made detailed statements accusing Cambodian government leaders

of numerous crimes.
