Four men who were arrested for the alleged murder of a family in Chet Borey district last week were released on Wednesday after police failed to link them to the case, said a police officer.

The four suspects – Choek Nou, 50, Choek Mao, 46, Choek Limsreng, 20, Mao Nhanh, 17 – all residents of Paer village, Thmey commune, Chet Borey district were freed after interrogation.

The Kratie provincial police had arrested them on August 13 in connection with the murder of the four family members in the same province which took place on the night of August 9.

Police said they were shot dead and their house was razed to the ground to destroy any evidence of the killings.

Kratie provincial police station crime chief Kim Heang told The Post that the suspects were detained because they lived in Koh Broem, located about 500m from the crime scene.
