A drunken fight in a New Taipei karaoke bar ended with police catching a man already wanted on money-laundering charges — a lucky break for prosecutors, bad news for him.

• A 33-year-old man drinking at a karaoke bar in Tamsui argued with a 70-year-old man at the next table and punched him.
• Police called to the scene late at night broke up the group and took three men in for questioning.
• A routine ID check showed the attacker was already wanted by prosecutors under Taiwan's money-laundering law.
• The older man suffered only minor scrapes; the attacker now faces both assault charges and the outstanding warrant.

Outlook: The case goes to the New Taipei prosecutors' office, where the money-laundering charge is likely to matter far more than the bar fight.
