A 77-year-old spy, known as Germany's James Bond for his secret missions during and after the Cold War, was convicted of tax evasion on Thursday and handed a suspended two-year sentence.

Werner Mauss, whose career spanned 40 years, says on his website that he was involved in smashing more than 100 criminal gangs and in the arrests of around 2,000 individuals.

In a trial that has been going on for about a year, Mauss — who wore a hooded jacket in court — was accused of concealing millions of euros from German tax authorities in offshore accounts between 2002 and 2011.
