I read about things like that happening in India and that law enforcement often won’t help.
I think the only option is to contact a NGO or non-profit organizantion that specializes in that. They’ll know what to do. Or a women’s refuge / shelter. India is kind of a big country so you’d need to look up something that’s available in the specific part of the country.
As I understand escaping this is difficult and needs to be planned and executed correctly.
Maybe call an organization like www.karuna.org they are a british charity. But they are nice and cooperate with project partners in India. Including some that specialize in sexual crime against women. Maybe they can give you some contact for emergency counseling.
But I haven’t checked those. 1091 seems to be the dedicated official helpline for women that got launched after a bad assault that got international media coverage in 2012. But that might not help since you already said police doesn’t help.)
