About Clarification For False Rape Case

one complainant gives false rape case on 7 members , 9 months already over, but now police called to the accusers to do sign on some papers and also they have informed they have made B -report on this case, but the accusers are all innocent they are not involved in this case in any way, so that my question is that, 1) can accusers are all go for police station to do sign for B- report? Second question is that , what type of case can innocent accusers lodge complaint on that falsely given complainant? because among accusers 4 are ladies, 3 are boys, they are all close relatives with complainant, she was lady, for the purpose of getting property illegally by accusers she made this rape case by plan . So what we have to do now give me suggestions sir.
