A man is due to appear at the Phnom Penh Municipal Court on Monday after being arrested on Saturday for killing his co-worker with a hammer in Kilometre 6 commune, in the capital’s Russey Keo district on Wednesday.

Deputy district police chief Iv Chhunpheng said police finished questioning the suspect on Saturday.

“I have already prepared the case,” he said.

Commune police chief Nhean Puthea said the 30-year-old suspect and the victim were both workers at The Cake House, a bakery located on National Road 5 in Kilometre 6.

The victim was from Andong Teuk commune, Botum Sakor district, Koh Kong province.

Puthea said the men had argued for months but there was no violence. On Wednesday morning, the victim went to drink beer and returned to the shop at around 8am. He spoke loudly making the suspect, who was trying to sleep, angry.

Puthea said the suspect hit the victim in the head with a hammer twice before fleeing the scene. He said the fatal incident likely stemmed from the old feud between the men.

Chea Vibol, the deputy head of the serious crime bureau at the Ministry of Interior, said on Sunday the suspect was arrested by his officers and Stung Treng police on Saturday while he was hiding at his sister’s house in Stung Treng town’s Stung Treng commune.
