Deutsche Bank CEO Target of Suspected Letter Bomb

A suspected parcel bomb addressed to Deutsche Bank Chief Executive Josef Ackermann was intercepted at a Deutsche office in Frankfurt on Wednesday, a senior U.S. law enforcement official said.

The package was discovered around 1 p.m. Frankfurt time (7 a.m. EST) in a mailroom, the official said. Initial analyses by investigators confirmed that it contained explosives and extra shrapnel, he told Reuters.

A spokesman for Deutsche Bank in New York declined to comment.

After receiving reports about the package, the New York Police Department stepped up security around Deutsche Bank's offices in New York and also notified corporate security executives around the city, the law enforcement official said.

The official said the suspected bomb carried a return address from the European Central Bank, which is also headquartered in Frankfurt.
