Four suspects—including the victim's wife—have been arrested for the murder of a newspaper editor sympathetic to the cause of the Khmer Kampuchea Krom ethnic group, police said Tuesday.
The murder of Pov Sam Ath was likely not political, Mok Chito, chief of the Ministry of Interior's Criminal Department, said.
Pov Sam Ath's wife, her son and two other men were being held, Mok Chito said.
The body of Pov Sam Ath, 29, was found April 25 stuffed in a trunk in the countryside, after the victim was beaten and asphyxiated.
Rights groups for the Khmer Kampuchea Krom had called for an investigation into possible political motives.
