Can I file an FIR against the same person at the same police station for different offenses like rape, kidnapping, assault, robbery, and criminal trespass, even after filing a complaint for hurt and intentional insult earlier?

Yes, you can file separate FIRs for different offenses against the same person at the same police station, even after filing an earlier complaint. Each offense is treated as a distinct incident, and you have the right to report them separately.
