Income Tax (I-T) officials on Thursday raided 187 locations belonging to relatives of jailed AIADMK leader VK Sasikala, her nephew TTV Dinakaran and organisations connected to them in several cities, said a senior I-T official.

He said the search is in connection with unexplained routing of cash post-demonetisation through shell companies connected with them.

Ten groups of I-T officials were involved in “the search exercise taking place across Tamil Nadu, Bengaluru, Hyderabad, Delhi and other places”, an I-T official told IANS preferring anonymity.

The raids began at 6 a.m. The tax officials also searched the residence of M. Natarajan, husband of Sasikala in Thanjavur, according to reports.

He said the I-T department will look at routing of funds within India and there are other agencies that look at routing of funds outside India.

The I-T officials are also searching the AIADMK Tamil daily Namadhu MGR.
