A Koran teacher in Cakung, East Jakarta, has been accused of sexually harassing 14 of his students.

"Every time the perpetrator [sodomized his students], he always gave them between Rp 1,000 and Rp 2,000," Comr. Didik Haryadi, a spokesman for the East Jakarta police, said on Thursday as quoted by Detik.com.

Didik said the teacher, 28-year-old Abdul Aziz Salam, chose his victims randomly and sodomized them after lessons were completed.

"He told other students to go home and then asked one of them to massage him. Afterward, he would massage the victim's waste and roll down their trousers," Didik said.

He committed these acts from December 2012 until April 2013, and he told his students not to tell their parents what he did.

However, in April, one of the students complained to his parents that he felt a pain in his backside and revealed to them that he was violated by Abdul. The confession sparked outrage amongst other parents, who asked their own children if they too were victims of the instructor.

Five parents of eight of the victims decided to bring the case to the police. The neighborhood unit chief then called the Cakung police to arrest the perpetrator, who was almost beaten by an angry mob.

Adj. Sr. Comr. M. Soleh, another spokesman with the East Jakarta police, said that medical examinations proved that the 14 boys were sexually harassed.

Last month, a Koran teacher was placed on the police's wanted list for allegedly raping and molesting three children in Ciputat, South Tangerang. The man, identified as Muhammad Firman, 25, worked as a teacher at a Tangerang mosque.
