Ahmad Imanuddin Sumar, who led the Abul Barokat boarding school on the island of Lombok, has been named as a suspect and detained by police. The development follows a BBC Eye investigation that detailed allegations of sexual abuse and showed how former students had gathered evidence in an effort to bring the claims to the authorities.
The report prompted public outrage and led to 12 additional former students giving testimony to police, according to the BBC. Central to the investigation were two former students, Ziadatur Rahmah, known as Zia, and Sukma Rohana Fajar. They launched their own inquiry after Zia told a former classmate that the headteacher had sexually assaulted her when she was 17.
The BBC's reporting is part of a documentary titled "Catching My Teacher," which examines efforts by ex-students to expose sexual abuse by teachers at Islamic boarding schools in Indonesia. The headmaster's detention marks a significant step in a case that had previously failed to progress through official channels.
