R.K. Nagar MLA Dinakaran's counsel has submitted a pen-drive to the Justice Arumuga Swamy Commission of Inquiry (COI) probing the mysterious circumstances leading to 2016 year-end demise of former Tamil Nadu chief-minister J.Jayalalithaa.

Govt. of Tamil Nadu constituted the COI in September last year. The Commission is functioning from its Ezhilagam Office in Chennai. It has already summoned a few politicians, bureaucrats, doctors and others who were in some way or the other connected with the former chief-minister during her 75-day long stint at Apollo Hospital, Chennai.

Dinakaran's counsel Raja Sendhoorpandi appeared before the COI yesterday and handed over the pen-drive containing videos related to the treatment given to the former chief-minister. Speaking to newsmen later, Sendhoorpandi said that he wasn't 'aware' of the contents of the pen-drive but only handed it over to the COI as instructed by his client Dinakaran.

It may be recalled that Dinakaran's supporter Vetrivel released a 20-second long video which reportedly showed the former chief-minister on a bed though doubts were expressed from many quarters about the genuineness of the video.

Jayalalithaa's former aide Poonkundran has, in the meantime, submitted to the COI a list of names and addresses staff members/servants (numbering 15) who were working at 'Veda Nilayam', the Poes Garden residence of Jayalalithaa at the time of her demise.
