The girl was brought to the All India Institute of Medical Sciences (AIIMS) from Hedgewar Hospital April 22, after she had taken an overdose of sleeping pills following her gangrape during nine days of captivity by her attackers.
"She took 16 sleeping pills last night around 2 (a.m.). She called our mother and told her that she was going to die, and then she fell unconscious," the girl's sister said.

Of the eight accused, seven have been so far been arrested.
The 13-year-old victim and her 12-year-old brother were abducted by two men known to her on March 15 from outside her house and taken to Loni on the city's outskirts.

The boy was released the next day. The girl was kept captive for nine days.
