FRANKFURT (Reuters) - German prosecutors have opened preliminary proceedings into alleged links between Morgan Stanley's
The Stuttgart public prosecutor's office said "sufficient and actual clues have emerged" suggesting ex-premier Stefan Mappus could have made himself liable to prosecution for breach of trust, while Morgan Stanley's Dirk Notheis could have made himself liable to prosecution for aiding and abetting breach of trust.
Notheis, 44, who ran Morgan Stanley's operations in Germany and Austria for more than three years, was granted leave of absence by the bank last month following an uproar over emails he reportedly exchanged with Mappus.
German newspapers in June published copies of emails Notheis reportedly sent to Mappus in 2010, when the southwestern state was trying to purchase a 45 percent stake in local utility EnBW from French energy group EDF
In the emails published by the newspapers, Notheis appears to give Mappus advice on how to limit time for political debate on a renationalization of EnBW, Germany's third-largest utility.
In a statement on Wednesday the prosecutor's office said several premises had been searched as part of the proceedings and a number of documents were seized.
"All of the accusations of breach of trust are without merit. And that is what the investigation will show", Notheis told Reuters.
A Morgan Stanley spokeswoman said in an emailed statement: "We confirm the presence of the Stuttgart public prosecutor's office in our business premises today. Morgan Stanley is cooperating with the public prosecutor's office during its investigation."
The reports prompted a wave of criticism, in part because they highlighted the cozy relationship between bankers and politicians when many Germans are angry about the role banks have played in the global financial and euro-zone debt crises.
The prosecutors also quoted a report by a government audit body which said the 4.7 billion euro ($5.76 billion) purchase price paid by Baden-Wuerttemberg for the stake in EnBW was at least 180 million euros too high.
According to the opinion of a separate report drawn up by auditors Warth & Klein Grant Thornton, which was mandated by the regional state's government to assess the deal, Baden-Wuerttemberg had overpaid by around 840 million euros, the state's government said in a statement.
In Germany, Morgan Stanley ranked second behind Deutsche Bank
Notheis' absence will be a blow for the investment bank, which had come to rely on him and his connections for lucrative advisory roles or mandates in merger and acquisition deals.
Morgan Stanley has won some big mandates from companies in which Germany retains an equity stake.
