A man fatally shot his wife Sunday night in a cafe in the Ikebukuro district of Tokyo, apparently in a fit of anger during a quarrel.

The suspect, whom police believe is a 54-year-old Chinese resident of Itabashi Ward, was collared on the street in front of the cafe by the eatery's employees, who later handed him over to police, according to news reports.

Initially arrested on suspicion of attempted murder, he was later booked for murder. Police believe the victim was his wife, a Chinese woman in her 50s. They have yet to determine exactly who she was.

The pair reportedly started to quarrel after entering the cafe together. At around 10:40 p.m., the man produced a handgun from his bag, stood up and shot the woman twice, in the jaw and the chest. She was rushed to a hospital but was pronounced dead.

There were more than 10 customers in the cafe at the time, but no on else was injured.

The eatery is about 300 meters northwest of JR Ikebukuro Station.

The suspect remained silent during police questioning, according to investigators.

Security camera footage from the cafe showed the man and the woman quarreling before the suspect began shooting.
