Police are searching on Friday for a Koran teacher who allegedly raped or molested three children in Ciputat, South Tangerang.

The man, identified as Muhammad Firman, 25, worked as Koran teacher at a Tangerang mosque. He reportedly invited a 14-year-old girl to his house in the Bukit Modern Hill housing complex last January. He allegedly raped the girl and threatened her, telling the girl not to tell anyone, police said.

Firman reportedly continued to rape the girl until the abuse was discovered by the girl's older sister. The sister read the girl's diary and discovered an entry detailing the rape. The family then reported Firman to the police and took their daughter in for medical tests on April 2, 2013. The doctor's examination confirmed the rape, according to reports in the Indonesian newspaper Tempo.

"There was an indication of sexual violence," South Jakarta Police spokesman Comr. Aswin told Tempo.co.

The girl's family told the newspaper there were more victims. "Beside my daughter, there are at least three other victims," the girl's father said. "They said that were groped and kissed by him."

Firman saw hundreds of students for Koran study. Three have come forward with allegations that the teacher sexually abused them.

Firman fled when police began to close in. He is believed to have run to Wonosobo, Central Java, Aswin said. "We're still hunting the suspect and we're waiting for the reports of other victims," he said.

After the allegations surfaced, local residents searched the man's room, discovering "magical" talisman, three pornographic videos, anti-pregnancy pills and one of the girl's outfits, police said.
