Federal prosecutors said today that police raided properties in the Berlin area on "initial suspicion of activity for an intelligence agency." They did not elaborate or specify what intelligence agency was involved, but said they had not made an arrest.
"We have investigations in two cases of suspected espionage, a very serious suspicion," government spokesman Steffen Seibert told reporters in Berlin. He declined to provide further details, citing the ongoing investigations.
Defense Ministry spokesman Lt Col Uwe Roth declined to confirm the reports, but said the case fell "into the ministry's area of responsibility" and that Defense Minister Ursula von der Leyen had been informed.
State Department officials traveling with US Secretary of State John Kerry in Beijing had no immediate comment.
German media have reported that he spied for the United States and came to authorities' attention when he recently offered his services to Russian officials in Germany by email.
The case has frayed relations between Berlin and Washington, which were already strained by reports last year that the National Security Agency spied on Chancellor Angela Merkel's cellphone.
The US ambassador to Berlin was summoned to the Foreign Ministry on Friday after news of that case broke. He was asked to help clarify the case.
