The Tamil Nadu Government has ordered an investigation into two letters sent by the Directorate of Enforcement (ED) levelling serious allegations of corruption involving senior DMK leader and Minister of Municipal Administration and Water Supply (MAWS) department, K.N. Nehru.

According to official sources, the Directorate of Vigilance and Anti-Corruption (DVAC) has launched a detailed inquiry into both the letters sent to the Director-General of Police (in-charge), G. Venkatraman, with copies marked to Chief Secretary N. Muruganandham. The ED had sought registration of an FIR and investigation into the alleged offences.

“Soon after receiving the complaints, the DGP (in-charge) forwarded them to the State Government for necessary action. After a detailed inquiry was ordered, the DVAC has launched an investigation into the allegations made by the ED,” a senior official told The Hindu on Wednesday (January 7, 2026).

The DVAC follows the procedure of registering a preliminary inquiry and then a detailed inquiry into complaints of corruption to establish prima facie offence before registering a case. “The ED has enclosed some documents in support of its allegations of irregularities in the award of contracts and job recruitment in one of the departments. We have to conduct our own investigation to establish the facts before proceeding further...this is the standard operating procedure,” the official said.
