Tamil Nadu cyber police: state and district contacts

Every district has a Cyber Crime Wing (CCW). On the Tamil Nadu Police contact page, choose Unit type 'District' and a Cyber Crime Division to see your district's CCW. The numbers there are officers' mobiles that change with transfers, so we link the page instead of copying them.

From the official police.tn.gov.in website. Checked on 3 October 2026. police.tn.gov.in Numbers on police websites change with transfers. If one does not answer, call 1930 or go to your nearest police station.

What to do first

1. If money left your account, call 1930 straight away. It works in Tamil Nadu and every other state, and it is the fastest way to get the money held.
2. Tell your bank to block your card, UPI and net banking, and report the transactions as fraud in writing.
3. Complete the complaint on cybercrime.gov.in with Tamil Nadu as the state, and save the acknowledgement number.
4. Keep screenshots, transaction IDs and the scammer's numbers, UPI IDs and links. Do not delete the chats.

When to contact the Tamil Nadu cyber cell

• You filed on cybercrime.gov.in with Tamil Nadu as the state and want to follow up on it.
• You are unhappy with how your complaint is being handled and want to raise a grievance.
• You need to know which police station or cyber police station is handling your case.
• Your bank account was frozen after a complaint and you need to know which police unit to contact.

The nodal officer contacts are for follow-up and grievances, not emergencies. For a crime happening now, call 112.
