AAP workers on Thursday staged a protest outside Home Minister's home and sought action against babus who assaulted MLAs inside the secretariat.
Earlier, Union Home Minister Rajnath Singh sought a report on the incident.
"The Ministry of Home Affairs (MHA) has sought a report on the incident from the Lieutenant Governor of Delhi. Justice will be done. A delegation of IAS DANICS and Subordinate Services of Delhi Government met me today (Tuesday) and apprised me of the prevailing situation," said Rajnath Singh.
The Union minister added, "I am deeply pained by the happenings involving the Chief Secretary of the Delhi Government. The civil servants should be allowed to work with dignity and without fear."
Delhi Chief Secretary said he was attacked in the presence of Arvind Kejriwal after being summoned for discussions on the government's plan to deliver key services to citizens' doorsteps.
However, the AAP refuted the allegations and termed them as 'ludicrous'.
