DMK chief M K Stalin Wednesday said the 'mystery' over late Chief Minsiter J Jayalalithaa's death persisted and asserted that if his party was voted to power people found guilty of causing her demise would be put behind the bars. Proper medical bulletins were not issued on her treatment and health condition, he said addressing people of a village here as part of the DMK's state-wide outreach programme of panchayats.

"Make a note, it will be my first task to find out who was behind her death and put them in jail after the formation of government by the DMK," he said citing the ongoing probe by a commission of inquiry into the circumstances leading to the death of Jayalalithaa on December 5, 2016 after prolonged illness. His comments come days after the commission raised several questions, including on why an angiogram was not performed on her during hospitalisation.
