"Violence took place on large scale, so naturally lapses have been there. We are trying to pin-point to what extent the officials were negligent," Singh told reporters here.
"We will soon complete the report," Singh said, adding after the report is fine-tuned, it will be submitted to the government.
It was up to the government to take action against those officials who were found erring in performing their duties, he said.
"The committee has eyewitness accounts, affidavits from many locals. We are going through district-wise details and trying to make the report accordingly," he said.
Meanwhile, Haryana's Agriculture Minister O P Dhankar said "definitely whosoever is found guilty when the report is out, government will take action against him/her".
Haryana government set up the Prakash Singh committee over a month ago.
