German federal prosecutors said Tuesday that a retired political scientist had been charged with spying for China for almost a decade.

In his everyday life, he was known as a political scientist who worked for the Hanns Seidel Foundation but in another life, he was an operative for the BND. A German broadcaster called this a “double-life.”

That was not part of his only double life. The 75-year-old man, who is being called Dr. Klaus L., allegedly spent nine of his 50 years as a spy, giving information to the Chinese secret service at a time that correlates with him also working for the German Federal Intelligence Service.

Prosecutors said in a statement that​ “he was approached during a lecture tour at Tongji University in Shanghai in June 2010 by members of a Chinese intelligence service in order to win him over for cooperation."

It is believed he started spying and getting paid by China in 2010.

“Subsequently, until November 2019, he regularly provided information to the Chinese intelligence service in the run-up to or after state visits or multinational conferences, as well as on current affairs,” the statement said.

His home was raided and his computers were confiscated for evidence.

According to the report, Klaus L. does not deny he worked with the Chinese and revealed his contacts with the Chinese to BND authorities after being raided.
