I am not from India but according to this link provided by NVC (

Police Records
Indian Police Clearance Certificates should be obtained as follows:
* All Indian IV applicants aged 16 and above, residing in India, should obtain police certificates from the local Passport Office. These are usually more dependable than those obtained at a local level and indicate that the subject had no serious criminal convictions on record at the time of passport issuance. Applicants whose Indian passport was issued within the past six months may present just the Passport Office Police Certificate, and need not obtain additional police clearances.
* Applicants over age 16, whose passports were issued more than six months previous to visa application, must also obtain a police clearance from the District Police Office serving the applicant's place of residence.
* Indian passport holders applying for visas outside India should obtain a statement from their local embassy or consulate confirming they have no criminal record.
* Non-Indian IV applicants residing in India should obtain police certificates from the District Police Station serving their area of residence.
* Indian police certificates are not available for foreign (non-Indian) applicants applying outside India.
