The Srivilliputhur Returning Officer made it public that the Flying Squad seized Rs 3.21 crores of unaccounted cash in the constituency.
Elections to the 234-member Tamil Nadu assembly will be held on April 6 and the counting of votes will take place on May 2.
In the 2016 assembly elections, the AIADMK had won 134 seats, DMK bagged 80 seats and Congress had managed to secure only eight seats. The BJP drew a blank.
The DMK hopes to stage a comeback in the polls after a ten-year stint in opposition. Nearly half of the 173 nominees are sitting MLAs and the DMK would be locked in direct contest with arch-rival AIADMK in over 100 seats.
The DMK, out of power since 2011, is eyeing a comeback by dethroning the ruling AIADMK and has stitched up a rainbow coalition comprising the Congress, the Left, MDMK, VCK and other smaller outfits, apportioning them a total of 61 of the 234 seats at stake.
