Set up in 2017, the commission has run into episodes of twists and turns and has inquired about hundreds of people who are connected to the hospitalization and the demise of Jayalalithaa.
While speaking to the reporters after interrogation, Sasikala said, "I have responded to the questions that were asked since the morning. The interrogation isn't over yet and it will continue tomorrow."
The summon to VK Sasikala has come days after the probing team had interrogated former ADMK MLA Aarukutty for nearly ten hours in connection with the case.
The resolution was passed in the assembly with the support of the DMK alliance while the BJP had staged a walkout from the house to oppose the resolution.
The incident has happened on Sunday outside the bustling Broadway bus station in the city. The police have suspected the political enmity behind the crime.
Edappadi Palaniswami and O Panneerselvam are still finding it hard to stand in the same line regarding the political future of the party and Sasikala's plan to take over the party.
The commission was set up based on the demand from Panneerselvam and now he has made an attempt to estrange himself from finding the fact of the final days of Jayalalithaa.
