Harassement

Hi Sir, I would like to understand on the proceedings that is taken in an Harassment case. Below are the details. My Sister got married on April 22nd 2018 and she was back with us by May 10th 2018. The guy was a lecturer and had a real bad mouth. He has always addressed her with parliamentary words and sexually harassed her. He has tied relationship with my 10 year old brother of mine and misbehaved with her in front of his mother and also threatened to shoot a porn video. His mother being a women did not even listen to her concern whenever it was brought to her attention. My sister was in her in laws house only for 4 days and he has shown hell to her. We have lodged a compliant with the Police on the harassment he has done and they have directed us to Family Welfare court for counselling. The counselling was attended by both the parties and counselling report stated that " there was no dowry harassment but they have physically and mentally abused" and the report has been sent to the Police. What will happen after the FIR is registered? Will that guy be arrested or what legal punishment is provided to for such act. Please brief us. Many Thanks Regards, Srikanth
