A 14-year-old girl died Sunday in another case of a lower-caste woman allegedly being raped by the same man twice in India, reports CNN.

The victim was kidnapped in May by the same suspect who allegedly attacked her in December of last year, according to a police report filed by her parents, a senior Delhi police official told CNN.

The suspect was reportedly out on bail while he awaited trial for his first rape of the teenager.

The girl belonged to the Dalit caste, Swati Maliwal, Chairperson of the Delhi Commission for Women told CNN, traditionally regarded as "unclean" and the lowest of the low.

Her parents told police she had been forced to drink chemicals by her alleged attacker.

She died on Sunday after being admitted to hospital in June after falling ill. The suspect was re-arrested following her death, police said.

The case comes soon after brutal details emerged last week of another attack on a Dalit student allegedly raped by the same group of men for a second time. News of the horrific double gang-rape caused an international outcry, raised questions around why the accused were granted bail, and highlighted the vulnerability of Dalit women in India.

According to India's National Crime Records Bureau, more than four Dalit women are raped every day, with 2014 statistics saying crime against Dalits rose 19%. In many of the cases, these crimes are committed by upper caste perpetrators.
