Around 7 p.m. on Monday, a man and a woman entered a café on Le Van Khuong Street.
They sat on the first floor, chatting with a third woman in a separate area inside the venue. After a while, that woman stood up and left.
Shortly later, the man and the woman who entered together started having a fight.
Suddenly, the man stood up, pulled out a knife, and stabbed the woman multiple times on her neck, causing her to collapse on the spot.
The perpetrator then stabbed himself multiple times. By the time people the incident was discovered, both had died.
Police are still investigating.
