 In 1990, Helbrans moved his community to the United States, which he claimed was due to his anti-Zionist views, and opened a small Lev Tahor yeshiva in Brooklyn where he gave Jewish study lessons to young students.In 1994, Helbrans was accused of assisting a 13-year-old boy named Shay Fima (or Shay Reuven) to go into hiding from his mother, a secular woman who had brought him to study at the yeshiva for his Bar Mitzva.The subsequent religious conflict that ensued led to Fima's becoming emotionally attached to Helbrans, who denied any involvement in the boy's disappearance.
