The former top Swiss private banker Rodolf Elmer was arrested Wednesday evening immediately after a Swiss court had set him free after finding him guilty of violating bank secrecy, dpa reported.
Prosecutors and the canton police said the issue leading to his re-arrest was once again suspicion of violating Swiss banking secrets.
Elmer, who has also been a WikiLeaks collaborator, was found guilty earlier in the day by a Zurich court of violating bank secrecy, attempted coercion and sending threatening letters.
The charges related to his time at Julius Baer Bank. Although found guilty, he managed to avoid the jail-time prosecutors sought. Instead, he received a fine of some 7,200 Swiss francs (7,500 dollars), suspended for two years. He will also have to pay court fees.
