(AP Photo/Michael Probst) (Newser) – An apparent mail bomb sent to the CEO of Germany's Deutsche Bank has raised security concerns on Wall Street as well, reports CNBC. The letter, which didn't detonate, contained explosives and shrapnel, and had been addressed to CEO Josef Ackermann. It got intercepted in the mailroom of the bank's headquarters in Frankfurt, notes Reuters. The NYPD, meanwhile, has ramped up security around the bank's offices in New York "out of an abundance of caution," said a department statement. Ackermann is described by Reuters as the "face of capitalism in Germany" and always travels with heavy protection. He plans to retire in May. Few other details emerged about the threat. The letter bore the return address of the European Central Bank, which also is located in Germany.
