J Jayalalithaa's niece Deepa Jayakumar on Wednesday told a one man panel probing the death of the late Chief Minister her aunt "may have been attacked."
She also wanted the panel to question the entire family of V K Sasikala.
After her three hour deposition before the Justice A Arumughaswamy Commission of Inquiry here, Deepa said she submitted her apprehensions over the circumstances leading to the hospitalisation of Jayalalithaa.
"I told the panel that there is no chance for her (Jayalalithaa) to get indisposed and get hospitalised (after attending work till nine pm). She may have been attacked," she told reporters here.
On September 22, 2016, Jayalalithaa was in good health and till nine pm that day, attended government work, Deepa, who shot to the limelight ahead of the death of the late leader last year, said.
All employees at the former chief minister's Poes Garden residence, including long time cook Rajamma, should be questioned, she said in her deposition.
"I submitted details on the circumstances under which my aunt was admitted to the hospital," she said and added that "all the family members of Sasikala should be questioned."
Sidelined AIADMK leader Sasikala, who was a close aide of Jayalalithaa, is now serving a four year prison term at Parappana Agrahara prison in Bengaluru in a disproprotionate assets case.
Jayalalithaa was admitted to Apollo Hospital here on the night of September 22 last year and passed away on December five, 2016.
Deepa also said a long time neighbour of Jayalalithaa apprised her that six persons not linked to the household were made to stay in the upscale residence.
This aspect should be probed further, she told the panel and added that the neighbor wanted his identity protected.
