A man who is accused of putting a fly into an energy drink to demand hush money from the maker will be held in custody for an additional four months for extended investigation, police said.
Vo Van Minh, a restaurant owner in Tien Giang Province, was arrested in January and alleged of appropriating property.
Senior lieutenant colonel Dinh Van Thanh of Tien Giang Police Department said they decided to extend Minh’s detention period in order to collect relevant evidence.
Minh claimed that there was a fly in his Number One bottle, a popular energy drink made by Tan Hiep Phat Company in Binh Duong Province.
He claimed the company agreed to give him VND500 million (US$22,900) in return for the bottle and as a compensation for him.
Minh was arrested on January 27 when he was receiving the money from the company, which reported him to the police.
Initial investigation found that Minh's Number One bottle could have been tampered with since the cap appeared slightly distorted.
In February, Nguyen Xuan Dinh, another customer from Tien Giang Province, also reported a "fly-like" object in another Number One bottle.
In the wake of Minh's arrest, he filed a complaint to the local consumer protection agency.
Following the incidents, Binh Duong Health Department inspected the company in February.
The one-day inspection has been criticized as being too short to find wrongdoings, prompting the Ministry of Health to launch a one-month inspection in April. Inspection results have not been made available, however.
The privately owned drinks company, one of the country's top beverage producers, has faced several food safety scandals, including customer complaints over its herbal tea Dr. Thanh and soy milk products.
In 2009, authorities found nearly 67 tons of expired food flavorings in the company's warehouses in Binh Duong Province and Ho Chi Minh City.
