The ex-boss of troubled Portuguese bank Banco Espirito Santo has been arrested on charges of money laundering and tax evasion.
70-year-old Ricardo Salgado ran the bank for 23 years before resigning after accounting irregularities were discovered at the bank's parent company.
The bank was family-run until the irregularities surfaced, but as confidence in the bank plummeted three family members were replaced.
Mr. Salgado had voluntarily acted as a witness in the investigation before he was arrested.
Banco Espirito Santo has been struggling recently and has seen its share price halve since April as a crisis gripped Portuguese banking.
The prosecutors office has indicated that there are several investigations centred on Espirito.
