While Dhinakaran has been blaming the BJP and estranged AIADMK leaders, including Tamil Nadu chief minister Edappadi K Palaniswami, for the tax raids and police action against Sasikala's family members, Jayaraman said he did not think the raids were politically motivated.
The offices of AIADMK mouthpiece Jaya TV, which is run by people said to be loyal to Sasikala, houses and offices of Sasikala's nephew Vivek Jayaraman and his sister, Sasikala's husband M Natarajan's house in Thanjavur, and Sengamalathaayar College in Thanjavur, owned by Sasikala's brother Divakaran, were among the 100-odd premises raided since Thursday morning.
Stating that the I-T officials had questioned him about the source of income for his wife's jewellery, he said he would submit documents to them within the next two to three days regarding the same.
"Sizeable volume of cash and documents have been seized at the searched premises".
A top tax investigation official in Chennai said that more than Rs 7 crore in cash and jewellery worth over Rs 5 crore were seized during the searches.
People who know Jayaraman or have watched him closely say he took over the management of Jaya TV previous year - after the death of chief minister J Jayalalithaa and around the time of the conviction of her aide Sasikala.
"No one was questioned today".
The department had summoned Karnataka's AIADMK leader V. Pugazhendi, whose premises were searched last week.
The official said the undisclosed income was in respect of the ten assessee groups, which includes Jaya TV and Midas Distilleries that are reportedly linked to Sasikala. His cousin T T V Dinakaran had, however, accused the BJP of using the I-T department against the Sasikala family.
Sasikala, now serving a jail sentence after conviction for corruption, was a confidante of late Tamil Nadu Chief Minister J. Jayalalithaa and lived with her for decades.
The I-T Department has been inquiring with several persons at its office in Nungambakkam.
Also, tax officials are yet to assess the value of immovable properties identified and the valuables in 15 lockers that are yet to be opened.
Several documents pertaining to benami transactions in the names of several household staff have been seized by tax officials.
