Tamil Nadu Police Online Complaint and FIR Registration: Chennai Guide

Residents of Chennai and other districts of Tamil Nadu can submit police complaints through the Tamil Nadu Police citizen services system. This guide explains how to submit a complaint, track its progress, distinguish a complaint acknowledgement from a registered FIR, and exercise legal rights under the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS).

Important distinction: Filing an online complaint does not by itself prove that a First Information Report (FIR) has been registered. The police assess the information under applicable law; confirm FIR registration using the FIR number and police station details.

Official Tamil Nadu Police online services

Start at the Tamil Nadu Police official website and follow the Citizen Services or online complaint facility. The Government of India also lists Tamil Nadu Police online complaint registration and online complaint status checking. Portal screens and required fields can change.

How to submit a Tamil Nadu Police complaint online

  1. Open the police portal. Use the official Tamil Nadu Police website and select the current online complaint or Register Complaint service.
  2. Select your district. Choose Chennai or the appropriate Tamil Nadu police district and relevant complaint category.
  3. Enter complainant details. Supply your name, contact number, address and email address as requested by the current form.
  4. Describe the incident. State when and where it happened, what occurred, the persons involved if known, and any immediate risk. Give accurate facts, not assumptions.
  5. Attach available evidence. Upload supporting documents or images only in formats and sizes currently accepted by the portal.
  6. Verify and submit. Complete any captcha or verification process, submit the complaint, and retain the acknowledgement or reference number.
  7. Follow up. Check complaint status online; if the facts disclose a cognizable offence, request the FIR details and copy from the police.

Do not rely on an outdated form's field limits, file size or email confirmation method; the live portal controls these requirements.

Legal provisions governing FIR registration in 2026

Section 173(1), BNSS: information about cognizable offences

Section 173 of the BNSS, in force from 1 July 2024, governs recording information relating to cognizable offences. A cognizable offence is an offence for which police may arrest without a warrant in accordance with the First Schedule or another applicable law. Information may be supplied orally or by electronic communication, irrespective of the area where the offence occurred (commonly called Zero FIR). Information sent electronically must be signed by the informant within three days for it to be taken on record under this provision.

Section 173(2), BNSS: free FIR copy

A copy of information recorded under Section 173(1) must be given forthwith, free of cost, to the informant or victim. A complaint acknowledgement, CSR reference and registered FIR are not interchangeable.

Section 173(3), BNSS: limited preliminary enquiry

For cognizable offences punishable with imprisonment of three years or more but less than seven years, the officer in charge may, with prior permission of an officer not below Deputy Superintendent of Police rank and having regard to the nature and gravity of the offence, conduct a preliminary enquiry within fourteen days to ascertain whether a prima facie case exists, or proceed with investigation.

Section 173(4), BNSS: refusal to record information

If the officer in charge refuses to record information about a cognizable offence, the aggrieved person may send its substance in writing and by post to the Superintendent of Police concerned. If the statutory conditions are met, the Superintendent may investigate or direct investigation. If that does not provide relief, an application may be made to the Magistrate as provided by law.

Read the BNSS on India Code and the Ministry of Home Affairs new criminal laws page. The older Code of Criminal Procedure, 1973, may remain relevant to proceedings governed by applicable saving or transitional provisions.

How to check complaint, CSR and FIR status

Use the police citizen services portal to select the relevant complaint status, Community Service Register (CSR) status or FIR status option, where available. Enter the acknowledgement or FIR number, year, district and station information requested. An online complaint reference shows submission or processing; an FIR number identifies a formally recorded FIR. Public access to copies or status information may be restricted in sensitive cases.

Frequently asked questions

Does an online complaint automatically become an FIR?

No. Submission and acknowledgement are not necessarily FIR registration. The legal duty to record information depends on the facts and applicable provisions, including Section 173 BNSS.

Can I report a crime outside my local police station area?

Yes. Section 173(1) allows information about a cognizable offence to be given irrespective of the place of occurrence, supporting Zero FIR registration.

Is an FIR copy free?

Yes. Section 173(2) provides a free copy to the informant or victim of information recorded under Section 173(1).

What should I retain after filing online?

Save the complaint acknowledgement, date, submitted narrative, supporting evidence and any subsequent CSR or FIR number.
