Authorities in Kampong Thom province have arrested a Military Police officer suspected of throwing a grenade into a prosecutor’s home more than three years ago.

Kampong Thom Provincial Court Prosecutor Ith Sothea said military policeman Sorn Pon, 35, was sent to jail and had his case forwarded to court on Thursday.

“We cannot say it was him 100 percent yet,” Sothea said. “We need to do more investigation. He might be the suspect in the grenade attack, but he has not confessed yet.”

Pon is suspected of throwing a grenade into the house of Kampong Thom Provincial Court Deputy Prosecutor Say Nora in 2014.

Nora, who was not home at the time, was not injured in the attack. At the time, he had been deputy prosecutor for just three weeks.

Nora and other court officials said the grenade was an attempt on his life by an illegal timber syndicate in the area after he oversaw a number of high-profile arrests of loggers in the group.

Court administration spokesman Van Seng said Kampong Thom and Preah Vihear Provincial Military Police acted on a warrant for Pon’s arrest issued last June accusing him of attempting to murder a public officer and using a weapon without permission. “First he shot the front of his house and then threw a grenade into his house,” Seng said.

Seng added that Pon had previously been convicted in absentia of illegally transporting and collecting timber in July 2016, for which he was sentenced to two years.
