Tokyo:
Tokyo police launched a murder investigation after a Chinese man was arrested for the brazen shooting of his wife at a cafe in one of Tokyo's busiest districts, police and news reports said on Monday.
The 54-year-old suspect, identified as Cao Jianping, was taken into custody shortly after the shooting in the capital's Ikebukuro neighbourhood on Sunday.
Security footage reportedly showed the pair embroiled in quarrel shortly before the shooting, a rarity in Japan where crime involving firearms is usually connected to yakuza organised crime groups.
A spokeswoman for the Tokyo Metropolitan Police on Monday confirmed that a Chinese national in her fifties was fatally shot in her chest.
Local media reported that the victim was the alleged shooter's wife. None of the other cafe customers were injured, Kyodo news agency said.
