Police in the Mekong Delta city of Can Tho said they have arrested a Taiwanese man who allegedly stabbed his Vietnamese wife to death after failing to convince her to return to Taiwan with him.
Lee Ya Te, a farmer in Tainan, was caught on Sunday afternoon when he was fleeing from the house of his parents-in-law, after the murder of his wife La My Hanh.
Police seized a bloodstained knife Lee carried with him and used to threaten locals who tried to stop him.
The 72-year old man told police that he had stabbed Hanh several times in her abdomen after she refused to come back to him.
Hanh, 48, succumbed to severe injuries on the way to hospital.
They got married in March last year. Hanh moved to Taiwan with her husband but flew back to Vietnam six months later and lived with her parents.
In February, Lee visited her and allegedly threatened to kill her with a knife.
Hanh first reported the incident to local police but then waived her complaint, enabling Lee to get off scot-free and return to Taiwan.
He came back three months later.
Neighbors of the victim said that she was a vegetarian who always lived in harmony with others.
Her marriage to Lee was her second, ten years after her first husband passed away.
