[S] I was SA'ed and am unable to do anything about it

POSTING THIS ON SOMEONE ELSE'S BEHALF!! So the above mentioned person met a guy through bumble. They talked for some months and some days ago the guy called her into his house. She went there as they were good friends already. There he offered her some drinks, she rejected many times but he forced her to drink. So she did. And after that he raped her. She was too scared to do anything. She lives in a pg in Delhi and is a student in Delhi University. Legal action cannot be taken as she can't let her family to get involved otherwise she will be called back home and would be forced to quit studies which she can't do. Also if the boy comes to know that she is doing such a thing, he can do something bad to her as he is delhi local and knows her pg address. The boy is 23 and an advocate. Need serious help from anyone in any way. Please contact if you or someone you know can help us in this matter. Any help or suggestion will be appreciated. She has a sister who can help her out as her guardian but parents can't be involved.
