Speaking to news agency ANI, her lawyer Pugalenthi said, “We want inquiry into it as she never showed such an attitude during her 30-year incarceration. We request CM to move her to Puzhal prison. She isn’t safe in Vellore prison”.

Notably, besides Nalini, others serving life sentence after being convicted for their roles in the former Prime Minister’s assassination are her husband Murugan, Suthenthira Raja alias Santhan, AG Perarivalan, Robert Payas, Jayakumar and Ravichandran.

Four of the convicts, including Nalini, are Sri Lankans. The other three are: Santhan, Payas and Jayakumar.

Rajiv Gandhi was assassinated by a woman suicide bomber of the LTTE on May 21, 1991, in Sriperumbudur, Tamil Nadu. The seven accused were convicted by a special TADA court and sentence to death.

However, the death sentence was later commuted to life imprisonment.
