Police are investigating what they described as a "suspicious delivery" addressed to Deutsche Bank chief executive Josef Ackermann, the bank said Wednesday.
Deutsche Bank spokesman Klaus Winker said police were alerted when the package was detected in the mailroom of the bank's headquarters among the cluster of skyscrapers that make up downtown Frankfurt am Main.
Frankfurt police confirmed a "suspicious item" was found among incoming mail at the headquarters around midday Wednesday, but refused to give any further details pending the outcome of an investigation into the package's contents.
Winker also declined to describe what was sent or to provide further information.
The New York Police Department said it knew about the scare. Spokesman Paul Browne said the NYPD received information early Wednesday that a letter bomb addressed to Ackermann had been detected by X-ray screening in the mail room. He wouldn't say where the information came from but said it was "reliable."
He added that the European Central Bank _ the governing body for the 17-nation common European currency _ was listed as the return address. The ECB's headquarters are located two blocks away, across a park where the Occupy Frankfurt movement has pitched its tents.
Browne said that New York police had dispatched patrols to Deutsche Bank offices in the city and issued warnings to banks around New York City "solely as a precaution." There was no evidence anyone was targeted in the city, he said.
Ackermann, 63, was awarded a negative prize on Wednesday by anti-lobby group Lobby Control _ based in the western city of Cologne. The bank chief was not present to accept the award that singled him out for allegedly cutting deals with German Chancellor Angela Merkel regarding efforts earlier this year to save Greece.
Deutsche Bank rejected the charges.
