He also claimed that he had been persecuted, and physically abused by the same Securitate as a member of the Jassy Group of anti-communist intellectuals, which included Dan Petrescu, Liviu Antonesei, Luca Pițu and others.
In October 2006, this sequence of scandals led him to resign from his position as head of the history department at the Central European University in Budapest, Hungary, and from the Pasts, Inc. Institute for Historical Studies.
As of 21 December 2006, Sorin Antohi is still an editor of the academic journal East European Politics and Societies, where his collaborator Vladimir Tismăneanu is chair of the editorial committee.
[2] At this time the scandal was, in part, revived by the Romanian-German author and Nobel Prize Winner Herta Müller who, in a letter in the Frankfurter Rundschau, asked how it was that Antohi, who had been an informer since the age of 19, and who had falsified his PhD diploma, had been invited to an event at a Romanian cultural institute in Berlin.
Antohi has also been actively involved in many institutional projects, focusing on the "education, training and career development of emerging scholars" from Eastern Europe.
