CBDT chairman J B Mohapatra will hold the charge of member investigations in the newly-formed board that frames policy and is the administrative body for the Income Tax Department, an official order said on Thursday.

The Central Board of Direct Taxes (CBDT), under the Union finance ministry, has two vacancies at present.

According to the order, Mohapatra, holding the additional charge of CBDT chairman, will have the "substantive" charge of member investigations, which has superintendence over the country-wide probe wings, intelligence and criminal investigation directorates of the tax department.

Former CBDT chief P C Mody and his predecessor Sushil Chandra also held the charge in an additional capacity during their tenures.
