Following inputs, a search operation was launched in the office block and a room used by jailed and deposed AIADMK leader V K Sasikala at "Veda Nilayam", the Poes Garden residence. Even as the raids were underway, Jaya TV CEO Vivek Jayaraman arrived at the Poes Garden.
Deepa Jayakumar claimed the raids were part of a conspiracy hatched by Sasikala.
The searches had court permission, the sources said. In the raids that lasted for five days, taxmen searched 10 "assesse groups", which included those linked to Ms Sasikala, her brother VK Divakaran and his associates, at 187 locations across Tamil Nadu, Andhra Pradesh, Puducherry and Delhi over suspected tax evasion.
The Friday's raids were seen as followup of the November 9 raids that were conducted in almost 200 locations.
More than ten IT officials were at Veda Nilayam, which Sasikala once shared with the late AIADMK leader.

These firms employ 300,000 people, have invested nearly €20 billion in India and account for nearly 1,000 operations throughout India.
Soon after the raid, heavy security has been deployed to avoid any untoward incident.
Poongundran's house was also raided earlier and he was summoned for questioning two times by the IT department.
He said Jayalalithaa's house was like a temple to the 1.5 crore AIADMK cadre.
Sources said the search was for possible unaccounted for wealth owned by Sasikala, who is serving a jail term for corruption.
Friday's searches are seen as a follow-up to the mega raids carried out by tax officials last week at Jaya TV and Sasikala's relatives.
