Phnom Penh - The Cambodian government on Monday launched an investigation into a helicopter crash that killed the country's controversial chief of police and three others on Sunday night.
Hok Lundy, a close ally of Cambodian Prime Minister Hun Sen, died along with deputy army commander Sok Sa Em and two pilots when their helicopter crashed en route to the police chief's home province of Svay Rieng near the Vietnamese border.
Government spokesman Khieu Kanharith said an investigation into the incident had begun but declined to provide any further details.
"We are unable to provide specific details until the investigation is completed," he told Deutsche Presse-Agentur dpa.
