The stock market in Vietnam has suspended trading of Halong Canned Food (Canfoco) shares following the detention of three Halong employees by police for suspected tax fraud.

The detained employees are alleged to have been involved in the falsification of seafood exports to China in order to claim value-added tax refunds.

Haiphong-based Canfoco cans seafood products and other foods and also makes animal feed.

Trading in the company's shares is suspended until further notice in order to protect investors.
