HANOI (Reuters) – Police in Vietnam have arrested a former senior executive of BIDV, a bank that has come under scrutiny from an anti-graft campaign in the communist-ruled country, the Ministry of Public Security said on Thursday.

Doan Anh Sang, former deputy chief executive officer of the bank, formally known as Joint Stock Commercial Bank for Investment and Development of Vietnam, was accused of “violations of regulations on banking operations”, the ministry said on its website. He is the latest in a series of former officials from the bank to have been arrested.

In a statement on Thursday, BIDV, one of Vietnam’s largest listed banks, said Doan’s arrest would not impact its “normal operations”.

“BIDV always abides by the laws and is cooperating with the authorities in carrying out necessary legal proceedings,” the bank said in the statement.

The bank’s former chairman, Tran Bac Ha was arrested in November, and according to the newspaper four other BIDV officials have also been arrested.

Sang’s lawyer was not immediately available for comment.

Sang was removed from his position at the bank in August amid a larger investigation into wrongdoings at the bank, the report said.
