False 420 case in trial court, being harassed

I was working full time and was going to apply for a master's program abroad.At that time my colleague's mother asked how I was applying,asked me to help with her son's process too. I helped them get an offer letter and appointment at the vfs. After I went abroad, she called me and told me that the visa was refused and the college wasn't returning her money.As I was abroad, she asked for my help. On contacting the college, I was told that they hadn't received the necessary documents to process the refund. I communicated the same to her. They kept sending incomplete documents and in the meantime started making claims that there is no college from where they sought admission in and I have taken their money from the college. Their own person volunteered too. I backed out from the process. They gave 4 police complaints and we were found innocent in all 4 enquires. Now she has lodged a criminal case under sec 420 in the trial court. We have got bail, what to do
