“When a girl or her parents approached them for termination of pregnancies, doctors at this hospital used to convince them assuring a safe and secret delivery,” an investigating officer said. “Once the baby is delivered and mother gets discharged, hospital authorities start hunting for gullible couples who could buy them.”

India has long been criticized for its poor women’s rights record. Human trafficking, violence against women, and rape are common in the country, where women comprise 48.3 percent of the population.

In 2012, thousands of protesters took to the streets of New Delhi, calling on police to protect women after a woman named Jyoti Singh died of injuries sustained while being brutally raped by six men on a bus.

Two out of three women report being sexually harassed in the capital, according to a report by the UN.

Numerous women’s rights groups, such as Sayfty, work to protect those at risk by educating women in matters of self-defense.
