Argoud was twice placed on trial and convicted (the first in absentia) of attempting to assassinate French President Charles de Gaulle.
Following the second trial Argoud was sentenced to life imprisonment, but released as part of a general amnesty in 1968.
On February 25, 1963, when Antoine Argoud was hiding in Munich after the failed August 22, 1962 assassination attempt on de Gaulle, he was kidnapped by French secret police CRS agents at the Eden-Wolff hotel, and smuggled to France à la Eichmann, where he was interrogated.
His revelation allowed the secret service to arrest Jean-Marie Bastien-Thiry and other assassins.
