Another case involved a 15-year-old girl from Bogor. She was recently rescued by police after being kidnapped by someone she met on Facebook and held at a restaurant, waiting for someone to move her to another town where she would be forced into prostitution.
In some incidents, the victims themselves ended up recruiting other young girls after being promised money or luxuries such as mobile phones or new clothes.
Police are trying to get a step ahead of the criminals. Detective Lt. Ruth Yeni Qomariah from the Children and Women's Protection unit in Surabaya said she posed as a teenager online and busted three men who used Facebook to kidnap and rape underage girls. She's searching for a fourth suspect.
"It has been getting worse as trafficking rings become more sophisticated and underage children are more easily targeted," she said.
The man who abducted the Depok girl has not been found, and it's unclear what happened to the five other girls held at the house where she was raped.
"I saw they were offered by my kidnapper to many guys," she said. "I don't know what happened. I don't want to remember it."
