Income Tax sleuths on Friday launched simultaneous searches at premises of Tamil Nadu Health Minister C Vijayabaskar and at least one MLA in connection with a tax evasion probe.
Officials said the searches were being conducted at over 30 locations in the state including against certain medical professionals, pharma firms and their executives.
Over 100 I-T sleuths along with security personnel are part of the operation, they said, adding premises related to officials of a medical university in the state are also being searched.
Searches have also been carried out against an MLA, officials said but did not give further details.
“The searches were being carried out in multiple locations, including Chennai and Pudukottai, following a tip-off about alleged tax evasion,” a source said.
Officials said there were certain “inputs” that black money is allegedly being pumped in for the by-election to R K Nagar assembly.
There were also several complaints of alleged money distribution by All India Anna Dravida Munnetra Kazhagam’s Amma faction.
The bypoll is scheduled for April 12. The seat fell vacant after the death of the then chief minister J Jayalalithaa and it is being viewed as a battle of prestige for the two factions of the AIADMK.
Vijayabaskar is a prominent loyalist of AIADMK-Amma faction’s candidate TTV Dinakaran.
Vijayabaskar, who is the first state minister to come under the lens of tax men, is among the key campaigners in the bypoll.
Officials said certain leads in the Sekhar Reddy case, the mining baron arrested for alleged financial irregularities post demonetisation, have also prompted the latest action.
