Amid allegations of a huge cash-for-votes racket in Tamil Nadu, officials of the Income Tax department visited the house of DMK leader Kanimozhi on Tuesday evening to "verify allegations of cash being stashed there," sources said. Kanimozhi, DMK lawmaker and the sister of party chief MK Stalin, is the candidate for the Tuticorin seat. It was alleged that "lots of cash" was stashed on the first floor of her house in Thoothukudi, sources said. IT sources, however, said later that it was a "false tip" and they drew a blank. No case has been registered.
