A man was stabbed to death in Battambang province allegedly by his wife yesterday after she caught him with a mistress in a shared rental house that his spouse knew nothing about.

Bran Sokuntea, 35, was allegedly monitoring her husband’s activities in Battambang district, and followed him to the rental home where she discovered his girlfriend.

“In fact, the suspect initially tried stabbing the girlfriend, but her husband intervened. His wife was jealous that her husband was living with the girlfriend more than with her and proceeded to stab him to death,” Im Dara, deputy commander of the province’s military police force, said.

The husband, Chub Bun Hong, 36, was fatally stabbed, while his girlfriend sustained minor injuries after fainting and was taken to hospital.

Following the murder, Sokuntea fled the premises and was later arrested by police.

Lach Bros, head of criminal offence research for the provincial military force, said the suspect claimed her husband’s infidelities caused frequent arguments, leading her to monitor his activities and discover the rental house.

“Police are investigating further for more proof,” Bros said, adding that the suspect will be sent to court today on murder charges.

The couple’s four children are under the care of their grandparents.
