Hok Lundy was born in Ta Pov village, Bavet commune, Chanthrea District, Svay Rieng Province to a family of Chinese-Vietnamese origin.

Hok Lundy returned to Cambodia following the fall of the Khmer Rouge, and served in various executive ranks under the People's Republic of Kampuchea in his home province.

He served as the governor of Svay Rieng Province for 9 months between January and September 1994, before was appointed as the National Police Commissioner.

[5] Heng Pov, a former police chief in Phnom Penh, accused Hok Lundy of involvement in over 70 deaths, including those of several high-profile Cambodian figures[6] such as Pisith Pilika; in return, Hok Lundy accused Heng Pov of involvement in several other murders, including that of a judge.

[9] Later independent investigations, possibly aligned with opposition political parties, have suggested that the crash may have been caused by sabotage or a missile fired from the ground.
