Elazar Rumpler, one of the Lev Tahor cult leaders, was arrested in El Salvador, as per Israel’s request.
Rumpler is wanted on charges of serious child abuse and attempted to leave Guatemala on a fake passport after previously being placed under a travel ban.
Guatemalan authorities have begun the process of extradition to Israel.
Rompler had previously been indicted in the Jerusalem District Court in May 2020 for the abuse of two children in the school where he served as principal in Canada between 2009 and 2011 before fleeing to Guatemala.
Various members of Lev Tahor have also been issued with INTERPOL Red Notices due to their risk of fleeing to other countries.
Large raid on compound
In December, Guatemalan authorities rescued 160 children and adolescents from the Lev Tahor cult in southeastern Guatemala after allegations of child abuse.
