Jaya TV and Dr Namadhu MGR have for decades functioned as the mouthpieces for the AIADMK and its now deceased supremo J Jayalalithaa.
A team of around 10 officials of the I-T investigation department entered the office of the television channel at Ekkatthuthangal around 6 am after showing their identity cards.
Apart from the office, IT officials are also searching Sasikala's nephew Vivek Jayaraman residence in Chennai and Jazz Cinemas, which is also owned by her family.
Meanwhile, in all the premises where searches were conducted, Tamil Nadu police provided security to I-T department officials.
Dinakaran, the sidelined AIADMK leader, blamed the Centre for the raids.
The raids are being conducted for alleged money laundering through newly floated shell companies.
Dhinakaran, who emerged out from his home, said his house was not raided by the Income Tax but some of his properties including a farm house in Puducherry were raided by Income Tax department due to political vendetta by the present government. "The raids are being carried out in 187 places", he said.
Dhinakaran, the deposed AIADMK deputy general secretary, condemned as a "conspiracy" the searches undertaken by the Income Tax department (I-T) mostly in Tamil Nadu and targeted the Centre. We will not allow the party behind the raids to spread roots in Tamilnadu, ' he said. Soon after IT authorities arrived at his home in Adyar in high-class south Chennai, Dinakaran said the raids were politically launched. "People who don't want us to remain in politics are threatening us through I-T raids".
MP R Vaithilingam, a key member of the ruling AIADMK group led by Chief Minister Edappadi K Palaniswami said, 'there is no relationship between today's raids and the issue of retrieving Two Leaves symbol.
Dinakaran and Sasikala head a group inside the decision AIADMK for control of the gathering, which right now is in the hands of boss priest E Palanisami and his agent O Panneerselvam.
