There is no indication the cases are linked.

Police have so far arrested two men in the case of the 11 year old from Panipat district, both of whom were neighbors of the child. They have also arrested two men in Sunday's gang rape case, and are on the hunt for two more.

Responding to accusations of police negligence, RC Mishra, a senior police officer in Haryana, told reporters Wednesday that "Rape is a part of society. This incident isn't just happening now, it's been happening for a long time."

Haryana Chief Minister Manohar Lal Khattar, the state's top elected official, called the incidents "unfortunate" and promised to "tie up all loose ends."

Change is slow

Singh's case shocked India, resulting in an intense period of media coverage and nationwide protests. Singh is commonly referred to as Nirbhaya, meaning "fearless" in Hindi.

In the month's following Singh's death, the central government passed legislative reform to increase penalties for sexual violence. This involved increasing the length of prison sentences and adding the death penalty.

In addition, the government set up fast-track courts and set up a $480 million budget, known as the Nirbhaya Fund, for new women's safety initiatives.

A little more than five years later, change is slow to manifest itself.

"Rape is all about patriarchal power and that kind of mindset takes a long time to change," said Sohini Bhattarcharya, president of Breakthrough, a non-governmental organization that works on gender issues in India and the US. "One Nirbhaya, one countrywide protest will not change it."

While the numbers show a clear rise in the number of sexual assaults, experts say the increase is at least partially due to increased awareness among women.

Speaking to CNN, Ruchira Gupta, the founder of Apne Aap, an anti-sex trafficking organization in India said that the data reveals women are "refusing to be silent," and that the "shame is no longer there." However, she cautioned that the figures likely represent only the tip of the iceberg.

"Large numbers of women are choosing not to report incidents ... because they don't trust the police, or the police are not registering the cases."

Sexual assault survivors in India continue to face obstacles when reporting incidents.

Under government-approved guidelines issued in 2014, that test, which supposedly determines whether a woman is sexually active, was declared scientifically inaccurate and irrelevant to cases of rape.

The report found that as of November 2017, only nine out of 29 Indian states had adopted the 2014 guidelines, which also advocate for long-term trauma counseling.

Barriers are exacerbated if the victim is from a poor family, or a lower caste -- as is the case with the spate of recent cases in Haryana.

In such cases, the report found multiple incidents where the police pressured women to settle their complaints for money, or choose not to register their complaints.

Speaking to CNN, Sandhya Gokhale, founder of Forum Against the Oppression of Women in Mumbai, claimed that most reports of sexual assault never make it beyond the police station. "It's only when it becomes so gruesome that (then) it's coming out," said Gokhale.

Even if a case is registered, getting justice in India's court systems is far from certain.

Courts and police both face a massive backlog of cases.
