Police in Vietnam's northern province of Cao Bang arrested a man who allegedly stabbed four people in a family to death after attempting to rape one of them on Monday.
Ly Dinh Khanh, 31, is alleged to have attempted to rape his 34-year-old neighbor early on Monday morning.
When she resisted his advances, Khanh stabbed her with a knife, and chased after her to her relative's house.
There, he killed the woman and her three relatives, a 86-year-old woman and two children, aged 2 and 6.
Khanh also burned down the house of the woman, police said.
He was arrested two hours later.
Local authorities have offered the families VND50 million ($2,232) as condolences.
The investigation is ongoing.
