I can't say much about India specifically, but in most countries in the world, you would proceed as follows:
- Use the formal rejection by the foreign country's embassy with the stated reason to file that with the police, so that they can mark the passport as invalid/duplicated/stolen in their system.
- Then, use the confirmation by the police to get a new passport with the autoroties while handing back the old one.
- Once the new passport has been handed over, the visa process can be repeated. Make sure to hand in a copy of the police confirmation of having the passport reported as being copied when applying for the new visa.
In a sense, the process should be the same as after having a passport stolen.
