A probe by Italian magistrates into scandal-hit bank Monte dei Paschi di Siena concerns only the lender's previous management, Siena public prosecutor Tito Salerno said in a statement on Wednesday.

Prosecutors in Siena, where the 540-year-old lender is based, are investigating allegations of corruption in the 2007 acquisition by Monte Paschi of smaller lender Antonveneta as well as fraud in connection to derivatives trades.
