No FIR may have registered but routine inquiry. Clear your mobile and don`t carry with you. Polcie will only warn you, no to do any such act and delete all her pics.
Well, you have committed a mistake so have to face little much. Either request her to take her complaint, you just in haste made such threat. If complaint withdrawn, no issue else go with local advocate.
And the ACP, cannot visit at present due to chances of covid effected.
