While 83 women were operated upon at Nemichand Jain Cancer and Research Centre at Pendari village of Takhatpur block on November 8, around 56 women underwent surgeries at three different camps in Pendra block on November 10.
The commission will investigate the case on number of points, including if standard protocol was followed at these camps, circumstances that led to the incident, whether medicines used at the camps were of standard quality, who are those accountable for this incident, measures that can be taken to avoid recurrence of such incidents and others, the statement added.
Earlier, the director of a drug company, which allegedly supplied sub-standard medicines that were administered to the victims of sterilization surgeries, and his son were arrested on Friday.
"Mahawar Pharma Pvt Ltd's director Ramesh Mahwar and his son Sumit have been arrested under Section 420 for cheating, based on a complaint lodged by Food and Drug Administration authorities," Raipur SP OP Pal said.

The FDA had on Thursday sealed a manufacturing unit of the company which supplied an antibiotic drug used at sterilization camps in Bilaspur district.
