A letter bomb was intercepted by Deutsche Bank empolyees in Berlin Thursday that was addressed for the bank's chief executive.
The bomb's target was Josef Ackermann, who is one of the most powerful figures in European banking.
A statement from the state police in Hessen reads, "the initial investigations show that this was a functional letter bomb," the New York Times reported.
The bomb was not detonated and no one was injured.
An Italian group called the Informal Anarchist Federation has claimed responsibility for the letter bomb.
A statement from the FBI reads, "we are working with German authorities to assess the incident in Frankfurt and any potential threat to facilities or people here," NBC reported.
Threats on executives of Deutsche Bank have been going on for a long time. They date back to the assassination of Alfred Herrhausen in 1989 during a bomb attack.
