Charged under pita and posco acts

Hi I was accused under various sections in Pita act and posco act . One I contacted a brothel house organizer and he shared me the photos of a girl( who is minor) and I said okay. And he called me continuouslyto visit. He asked me to come to the place and i went. I rang the door bell. But the task force police who are already present forcefully took me in to the room and booked a case. Here I didn't even committed the crime and didn't even saw the girl but booked under Pita and Posco acts. I am a working professional and don't even have a single traffic channel. Now I am seriously worried about the case as it spoils my career.please suggest me a better way to get out of this case and prove that I didn't commit any crime.I didn't even saw the girl but a case was filed . Please help me with the information
