Harrassment of wife by nebouring shopkeeper.

We have a shopkeeper dealing in tobacco pruducts just opp. our shop of computer parts. My wife also sits with me as I look the outside market. His wife also sits there. Few time my wife objected to people smoking there, but those people instead of stopping their clients just abused her. Then they complain to SSP office with help of some market leaders who also use to smoke their and who are my competetorsabout my sign board also some false allegations about my wife. Then we pressurise by market leaders and beat Box constable to give compromise. Then they got me written on blank paper that I will remove my sign board.They also assured that nobody will smoke around our shop. Next day my wife noticed that people are still smoking out side our shop then she tried to click some photographs of that. Then they both husband and wife started abusing her in very dirty language. I also made some audio and video recording of that. Then in police station we were told to compromise other wise we will be arrested under section 751. Being a God fearing people we compromise just to avoid being fear of arrest. Few months back both husband and wife again abused my wife when she was alone at shop but again she was forced to enter into a compromise by police. I written to IG of police about this but no action was taken against them and again after some time when me and my wife was alone at my shop they along with their son and some other unknown people assaulted on me and my wife and threatened us to kill us because of my complaint. I also made some video recording of it. Then we called at women helpline and we called to police station where I showed them video recordings but again we were told to compromise otherwise we will be arrested. Again when we were use to sit in police station for few hours then we compromised just because the fear of arrest. Now those people along with some market leaders abuse us on regular basis and smoking around our shop increased to many folds. We also not allowed to install CCTV cameras around our shop as they says their privacy got disturbed by this. So I want legal advice about this.
