Forced Arranged Marriage

Hello Sir, I am Avinash Jha lives in Bangalore and working in Future Group and My Girlfriend Ekta Chaudhary also lives in Bangalore and works in Raymonds. We are in relationship from last 1 year and 3 months. I talked to my family and they are ok with this but My Ekta's parents are not OK with it. She told them in Last september and In november, Her father died due to Heart stroke. After that, everyone started blaming her for her father's death. When she told them in September about me, On that visit, They asked us to see a boy for arranged marriage. After her father died, everyone started telling her that your marriage was his last wish, get Married with that boy. She kept refusing this. They threatened her that they will disown her, she told ok. Then they asked her to visit them, She refused. Then her sister told her that her mother is not eating anything and she will also die soon, so she should go and meet her mother. She thought It's about her mother, so, She went to meet her in Ahmedabad, where her family stays, But they took her forcefully to Barmer, Her native village and forcing her to get married. She can't run away also, Because they have taken her ID's, ATM cards and documents. She is badly stuck there. When she found no way to leave that place, then she told, Ok, She will get engaged, but next day she will go to Bangalore and marry later. Her family agreed on this, but now they are secretly planning to not to let her go. She heard it, when they were talking. Pls suggest what Can We do In this situation. She still has her phone with her, but I doubt, they can take it after engagement. Pls help.
