Raids were conducted on 13 houses in Ho Chi Minh City on Sunday morning and around 7 billion dong (US$400,000) in betting money was found, a city police officer told The Associated Press on condition of anonymity as he was not authorised to speak to the media. The ring, which had been operating since last year and had connections with betting companies in Hong Kong and Macau, offered bets on European football matches, he said.
