According to an official, the minister apprised the Lt Governor of the incident seeking action in the matter.
Hussain was yesterday mobbed by more than a hundred officials and staffers, hours after Chief Secretary Anshu Prakash was allegedly manhandled at the chief minister's residence.
An FIR has been registered against unidentified people in connection with the case.
