According to the country’s security office, police in Vietnam have charged a deputy health minister for his alleged involvement in a bogus pharmaceutical trade conspiracy.

Truong Quoc Cuong, 59, is the current head of Vietnam’s medicine and cosmetics management. He has been a deputy minister since 2016.

In a statement, the police-led Ministry of Public Security said he was charged with “lack of responsibility, resulting in serious repercussions.”

It was unclear whether Cuong had been detained.

The health ministry did not immediately respond to a request for comment, while calls to Cuong’s phone went unanswered.

Citing unnamed police sources, state media outlets said Cuong had been detained.

Voice of Vietnam Radio said the alleged offence took place in 2014 when Cuong was head of the Drug Administration of Vietnam.

Giao Thong newspaper, run by the transport ministry, said Cuong had permitted a local company to import over 54 billion dong ($2.38 million) worth of fake medicine for domestic sale.

The Ministry of Public Security did not immediately respond to calls seeking further details of the prosecution of Cuong.
