New Delhi: A 14-year-old Dalit rape victim who was repeatedly sexually assaulted and was forced to drink corrosive substance, died at a hospital on Sunday.

The accused - Shiv Shankar - has been arrested. Delhi Commission for Women (DCW) Swati Maliwal chief lashed out at the Centre and Delhi police on the issue of women's safety.

"How many Nirbhayas does Delhi want? We all simply wait for next Nirbhaya to die," the Delhi Commission for Women (DCW) Chairperson Swati Maliwal said on Twitter, adding she "never felt so helpless."

She died just now. Delhi again failed her Nirbhaya. She suffered so much pain. N her perpetrators were roaming free! https://t.co/wImFxjcPyz — Swati Maliwal (@SwatiJaiHind) July 24, 2016

"The girl was fed a corrosive substance which completely destroyed her internal organs and she died a very painful death," she said, adding that it was only after the Commission issued notice to the DCP (North), the accused who was roaming free was arrested.

She asked the Centre to set up a high-level ministerial committee on women safety under the leadership of Home Minister Rajnath Singh.

"To add insult to injury, Home Ministry scrapped Women Safety Sp Task Force in Delhi set up wen Nirbhaya died stating it's mandate finished!

"She is dead ! We the system is responsible. Never felt so helpless. Need to do something. Come on people ...(sic)," Maliwal said in a series of tweets.

Maliwal was alluding to the Centre's recent decision to disband the Special Task Force on women's safety in Delhi. It was established in 2013 in the aftermath of the brutal Nirbhaya gangrape.
