In one particularly shocking case, police in the capital, Delhi, have arrested a man in his 30s for the rape and assault of an 86-year-old grandmother.
"The woman was waiting outside her home on Monday evening for the milkman when she was approached by her attacker," Swati Maliwal, head of the Delhi Commission for Women, told the BBC.
"He told her that her regular milk delivery man wasn't coming and offered to take her to the place where she could get milk."
The octogenarian trustingly accompanied him, said Ms Maliwal, adding that he took her to a nearby farm where he raped her.
"She kept crying and begging him to leave her. She told him that she was like his grandmother. But he ignored her pleas and assaulted her mercilessly when she tried to resist and protect herself," Ms Maliwal said.
Local villagers who were passing by heard her cries and rescued her. They handed over the attacker to the police.
Ms Maliwal, who visited the survivor at her home on Tuesday, described her meeting as "heart-breaking".
"Her hands are totally wrinkled. You get a shock when you hear what she went through. There are bruises on her face and all over her body and she told me that she had vaginal bleeding. She is suffering from extreme trauma."
May Allah protect us from this creatures
