The Taipei District Prosecutor's Office said in a statement that Yeh Sheng-mao, the former Bureau of Intelligence chief, allegedly concealed documents detailing suspicious financial transactions that had been provided by the Egmont Group, The Washington Post said Friday.
Prosecutors alleged in Thursday's indictment that those documents contained information regarding money-laundering and the daughter-in-law of former Taiwanese President Chen Shui-bian.
The Post said $20 million was allegedly wired to a Swiss bank account controlled by the woman from Chen and his wife. The source of those funds is being investigated as allegations of possible corruption have surfaced.
The newspaper said for his alleged part in the suspected money-laundering scheme, Yeh is facing 2 1/2 years in prison if convicted of the charges.
