BERLIN -- Police say someone removed faucets from the still-incomplete headquarters of Germany's foreign intelligence service in Berlin, causing a large water leak.

Police spokesman Michael Merkle said officials were alerted to the theft at the sprawling site on Tuesday. He couldn't say how many taps were stolen.

Merkle said Thursday that police have no information yet on who might be responsible, and haven't found traces of a break-in.

The Federal Intelligence Service, better known by its German acronym BND, is moving its headquarters from the Munich suburb of Pullach to the newly built complex in Berlin. The move is expected to be complete by 2017.
