The Additional Chief Secretary in the Welfare Department is likely to begin his probe tomorrow, which the government had ordered on Sunday. The government has asked him to complete the probe and submit report at the earliest.

Sachivalaya sources said the terms of reference included an ``administrative inquiry into the whole incident to ascertain its facts and collect relevant documents from the police and the Civil Supplies officers concerned''. Das will also analyse the most important aspect of relations between a public functionary (in this case the deputy minister) and a public servant (civil supplies officers).

The sources said he would find out at whose instance the officials had left Gandhinagar for Vejalpur, and panchas (witness team usually present during such raids) had accompanied them.

Besides, Das will look into the allegations by the officials that Chauhan and the millers had attempted to ``offer bribe and obstruct government servants from performing duties", besides the two complaints, one by the traders with Vejalpur police and the other by the officials with Gandhinagar police, and record statements of Chauhan, the traders and the officials.

Whatever may be the outcome, it is likely to unfold some interesting developments, especially when Civil Supplies Minister Jaspal Singh has already vouched ``to support my officials to the hilt to keep their morale high''. Singh had on Monday defended his officials, admitting it was at his instance they had gone to Vejalpur. ``I have full faith in my officers who will never do anything that may tarnish my department's image'', he had said.

As announced earlier, Chauhan has not been attending office since the day the government ordered the inquiry. ``If Chauhan is innocent, he should start attending office'', Singh had remarked on Monday, when his attention was drawn to Chauhan's statement that he would not attend office till the probe was completed.
