ok let me correct myself, hoisting flag is not a criminal offence, as per the police report is actually:
6 held for hoisting Pak flag over dargah - Vadodara - City - NEWS - The Times of India
The complaint, which was filed under Section 153A of Indian Penal Code, has been clamped for promoting enmity between different groups on grounds of religion, race, place of birth, residence, language among others and doing acts prejudicial to maintenance of harmony.
