A German citizen was arrested at Munich airport on suspicion of treason for allegedly passing intelligence onto Russia, the prosecutor general's office said on Thursday.
The man, identified as Arthur E., was arrested on Sunday upon arriving in Germany from the United States, the prosecutor said in a statement. He is said to be an associate of Carsten L., an employee of the German foreign intelligence service (BND) who was arrested in December on suspicion of spying for Russia.
Arthur E., who is not a German intelligence employee, is believed to have passed onto the Russian intelligence service information he had obtained from Carten L., according to the prosecutor's statement.
