NEW YORK -- The NYPD is warning New York banks to concentrate their security efforts on mailrooms after a letter bomb was sent to the CEO of Deutsche Bank in Frankfurt, Germany, NBC New York reported.
All New York banks are "being advised to take precautions" Wednesday after the device was detected in the mailroom of Deutsche Bank's headquarters overseas, an official said.
No one was injured.
According to NBC New York, the NYPD warning to bank security officials reads in part:"We have received a report of a confirmed mail (package) explosive device that was addressed and sent to ... Deutsche Bank in Frankfurt, Germany. The package was detected by X-ray technology inside the mail room. The package did not detonate."
NYPD officials are stepping up security around Deutsche Bank locations in the city. There was no immediate word on what individual or what group sent the apparent letter bomb, the official said.
"The FBI's Joint Terrorist Task Force is aware of the matter and is consulting with its partners in the law enforcement and intelligence community," FBI spokesman Jim Margolin said.
Germany's Deutsche Bank confirmed on Wednesday it had received a suspicious envelope and handed it over to the police for investigation. "We confirm that a suspicious envelope has been sent to Deutsche Bank," a spokesman for Germany's biggest lender said.
A police spokesman in Frankfurt declined to say what was in the envelope but said a bomb disposal expert had been sent to the headquarters of Deutsche Bank, Germany's largest bank.
Frankfurt police spokesman Alexander Kiessling said: "There was a piece of mail that arrived at Deutsche Bank that was noticed. It was noticed because it seemed unusual."
Ackermann is the face of capitalism in Germany and is one of the few senior managers in the country who is always surrounded by bodyguards. He is due to retire in May next year after more than 10 years at the helm of the bank.
A U.S. law enforcement official told Reuters that the package had been discovered in a mailroom around 1 p.m. Frankfurt time (7 a.m. EST) and contained explosives and shrapnel.
The official said it carried a return address from the European Central Bank, which is also located in Germany's financial center.
Banking sources said the bank had stepped up security measures around the world.
