German authorities have arrested a 31-year-old-man under suspicion of being a double agent employed by the US's National Security Agency (NSA) to report back with information.
A report on Reuters, which claims access to two government sources, says that the man worked for the local domestic intelligence agency (BND), and the NSA. A statement released by the German government, and seen by Reuters accepts an arrest but stops short of more detail.
It appears the man who has been arrested may not have had access to much information. Reuters' source suggests low ranking access to information.
"This was a man who had no direct contact with the investigative committee... He was not a top agent," said one of the sources.
We have asked the NSA if it is making comment on the arrest but so far it has not responded.
A German paper called The Süddeutsche Zeitung has more information. It says a German government spokesman described the US's attempts to monitor the country as a "very serious operation".
It said German chancellor Angela Merkel, who has already complained about the NSA and PRISM and spoken to President Obama about her concerns, is aware of the situation but has declined to comment.
Süddeutsche Zeitung said that the individual was first arrested on suspicion of spying for Russia but revealed his relationship with the US during questioning. It added that the claim is being investigated.
Last year Germany accused the NSA of bugging Chancellor Merkel's phone. Then the German leader was said to have "unequivocally disapprove" of the intrusion.
