Police are still investigating after an unknown gunman shot into the Tuol Kork offices of the opposition party early Saturday morning.

Cambodia National Rescue Party spokesman Yem Ponharith said yesterday that “no leads” had been made following a police investigation Saturday.

“The police, military police and experts went down to the office to investigate and interview the security guard and his son, who stayed overnight,” he said.

“The party is waiting for the results of the investigation.”

On Saturday, at about 3am, a single shot was fired through the window of the office in which a guard had been sleeping. No one was injured, but the party decried it and called for a thorough investigation.

National Police spokesman Lieutenant General Kirt Chantharith told the Post on Saturday that it was premature to claim the crime — which occurred less than a day after the return of opposition leader Sam Rainsy — was politically motivated.

“Until we have something more, we cannot say,” he said.

Addressing the shooting on his first official campaign stop, Rainsy told supporters Saturday in Kampong Speu that he condemned “all forms of threats”.

“They should respect the will of Khmer citizens who are peacefully respecting the law together by not secretly shooting, robbing or causing any violence,” he said.

On Friday, Rainsy returned to Cambodia following nearly four years in self-imposed exile. An estimated 100,000 supporters thronged the streets to greet Rainsy, who vowed in a fiery speech to “rescue” the nation.
