MIAMI (AP) - Another former banker at UBS AG has been charged with conspiracy to defraud the United States.
    
According to an indictment filed Tuesday, Martin Lack helped U.S. customers open and maintain secret bank accounts in Switzerland.
    
U.S. officials say Lack offered clients falsified bank documents to conceal the source of the funds in their undeclared bank accounts.
    
The indictment also alleges that Lack sent another former UBS banker, Renzo Gadola, to meet with a client at a Miami hotel in November to prevent him from disclosing his secret account to the IRS. Gadola pleaded guilty to a tax conspiracy charge in December. He will be sentenced later this year.
    
Lack faces a maximum of five years in prison. Court records did not show whether the Swiss citizen had a U.S. attorney.
