Perpetual Injunction order - Execution Procedure

Dear all, I had an urgent query to be addressed on emergency. I got perpetual injunction order from nalgonda District court against a defendant on frequent trespassing in to my property last month. He even accepted in front of judge while cross exm , that he is trespassing in to my land. Hon'ble court granted me permanent Injunction order after 3 years trial. But, Defendant is still Trespassing in to my property even after hon'ble district court injunction order. When I contacted my lawyer for implementing the injunction order, he is asking to file FIR against them , only then we can file for execution order. Is this true that I need to file case, as police are not filing case and asking me to get implementation order and only then they will stop the defendant from trespassing in to my property. How should I proceed in this scenario. I captured photos, videos of defendant trespassing in to my property.
