The French prosecutor fined Swiss bank UBS for 3.7 billion euros ($ 4.2 billion) for his role in a major tax evasion.
"Tax evasion, deliberate stealing of the company," while the Swiss bank is on trial, was followed by French accusations of involvement in money laundering linked to tax evasion for several clients, Attorney General Eric Russo said.
The Swiss bank's trial began in France on Monday.
The bank faces charges of aiding a number of wealthy Frenchmen to hide 10 billion euros of French taxes.
For its part, the bank said before the trial that it would defend itself against these unfounded accusations.
