Police in the South Korean capital Seoul Sunday arrested a Vietnamese man for allegedly stabbing his girlfriend to death and severely injuring her mother the night before.
The 27-year old man, whose identity has not been disclosed, has been accused of stabbing the two several times in District Guro.
Police rushed his girlfriend, 29, and her mother, both Vietnamese too, to a hospital, but the former succumbed to her severe injuries.
Investigators said they are looking into the cause of the attack.
According to a Facebook page belonging to the Vietnamese community in South Korea, the woman, a native of the Mekong Delta city of Can Tho, was killed soon after she told her boyfriend she wanted to end their relationship.
In December police in the same district discovered the bodies of a Vietnamese woman, her Korean ex-husband, and their daughter on a road.
Investigators later said the man had killed the two and then himself.
