In the wake of shocking revelation on the suspicious involvement of the top police officials of Tamil Nadu in the row of corruption in letting the Gutkha companies manufacture banned Gutkha products in the state, the Enforcement Directorate, India's economic intelligence agency, had summoned T K Rajendran, retired Director General of Police, Tamil Nadu and Assitant Commissioner of Police along with top police officers to appear before the agency by the first week of December.

The city's office of ED had nested former Chennai city commissioner S George, Deputy commissioners of Police Vimala and Jayakumar and Assistant Commissioner of Police Mannar Mannan and a few other inspectors for the investigations towards the scam that had quaked the credibility of the police department. While investigating the top police officers, the agency would also be interrogating the officials from the state's food safety and excise departments in the case.

These high ranking officials have been under the scanner by the intelligence agency for their alleged connection in obtaining a quid pro quo towards consenting the manufacture and sale of Gutkha products in Tamil Nadu that were banned in the state since 2013. They have been accused of taking bribe from the manufacturing companies to produce, store and to sell the banned Gutkha products in the state. After the allegations come to the spotlight, the state directorate of vigilance and anti-corruption took the case for investigations after which the case has been transferred to the Central Bureau of Investigation that conducted the searches in the residences of the then DGP Rajendran, Chennai commissioner George and the sitting Health Minister C Vijayabaskar in September 2018. 

Inline with the investigation of CBI, the Enforcement Directorate has attached the properties worth Rs 246 crore in connection to the case. The reports say that the attached property includes movable and immovable properties across Tamil Nadu, Andhra Pradesh, and Puducherry. With accord to the directives from the Madras High court, the Enforcement Directorate had conducted an inquiry on the FIR filed by the CBI in May 2018.

In 2016, the Income Tax department, by having the inputs, conducted the searches on the properties of the manufacturer of gutkha and pan masala in Sengundram which is in the outskirts of Chennai for allegedly concealing the taxes for Rs 250 crore. During the raid, the IT department had uncovered a diary from the place which carried the names of those who had received a bribe from the manufacturer towards producing and selling the Gutkha products. Those names include the state health minister Vijayabaskar, high ranking police officers including the DGP and the Commissioner, multiple officials in the food safety and excise departments. After the search, the case has been filed against Madhava Rao, the manufacturer of the banned products and these officers, minister, and the authorities have been under the drones of the investigations, under the fierce criticism by the opposition parties and by the state people since the allegations came to the spotlight.
