NEED SERIOUS ADVICE

I NEED TO KNOW THE RIGHT WAY TO DEAL WITH A ISSUE A PERSON WAS FORGING MY SIGNATURES FOR MY SHOP ON THE OTHER HAND WAS SENDING GOONDAS TO GRAB MY SHOP. WHEN I PUT A COMPLAINT IN THE POLICE STATION THE POLICE STARTED HARASSING ME AND ADVISED HIM TO FIND A HIDING PLACE BY FALSELY PUTTING A CASE IN COURT SO THAT THE COURT PUTS A STAY ORDER ON MY SHOP. I DONT WANT TO GET INTO HIS WICKED MEASURES.THE DATES ARE BEING GIVEN SINCE 2016.DO I NEED TO ATTEND THE COURT HEARINGS.ALL PAPERWORK IS CLEARLY AND LEGALLY IN MY NAME.ALL THE AREAS ASSOCIATED WITH MY PROPERTY HAS WARNED HIM WITH LEGAL MEASURES IF HE COMES NEAR THE SHOP OR COMES TO TRY TO PAY THE RENT OR DEAL WITH ANY LEGAL DOCUMENTS.DO I NEED TO GO FOR THE COURT DATES AND IF YES HOW CAN I DISCONTINUE THIS ACT OF NUISANCE VALUE WHICH IS GREATLY DISTURBING MY DAILY LIFE.A CRIMINAL IS HIDING UNDER THE NOSE OF THE COURT WHEN I HAVE ASKED THE POLICE TO ARREST HIM.PLEASE ADVISE,AWAITING YOUR REPLY.THANK YOU
