Daniel Ambash (1955-) is a Franco-Israeli citizen and follower of Rabbi Yisrael’s revitalization movement within the “Na Nach” BresloverHasidim. Since his arrest in2011, he has been serving a 26-year prison sentence. He is portrayed in the Israeli media and in the judgments of the District and Supreme Courts as a sadistic cult leader who enslaved his six wives and his children through the mental manipulation techniques of brainwashing, thereby compelling them to participate in deviant sexual practices and heinous acts. This study explores the anti-cult narrative that shaped the police investigation and the legal process, and how Israel’s new anti-slavery legislation was combined with brainwashing theory in order to convict Daniel Ambash. The role of Israel’s anti-cult group, the media, the police and Social Welfareare analyzedwithin the theoretical frameworks of Stuart Wright’s model (1995) of counter-movement mobilization and Stanley Cohen’s concept (1972) of “moral panic”.
