Officials have arrested three more suspects in connection with Sunday night’s mob killing of Seng Rothy, 33, in Prey Veng province.

Rothy was beaten to death by villagers after an argument with three other men escalated. Rothy’s nine-month pregnant wife was also hospitalised after being injured in the melee.

Seng Ponlork, Peamro district police chief, said that one of the men arrested, whom he identified only as Virak, was the son of the Neak Leung village chief.

Nguyeng Yang Neu, 27, Nguyeng Yang Korng, 30, and Lang Yang Serng, 22, were arrested after the initial altercation.

Yesterday morning, police also arrested Virak, and two men identified as Suy and To Yang Phoc.

According to Ponlork, two of the suspects told police they joined the mob because they heard Ngueng Yang Tev calling for help while covered in blood.

The suspects are being detained at Peamro district police station but will be transferred to Prey Veng Provincial Court to face charges.

“Authorities will continue to investigate and arrest more people involved in order to bring them to justice,” Ponlork said.
