Bramhananda Reddy, an Indian Railways Accounts Service officer, at present posted in Kolkata was called here and arrested by the CBI after intense questioning over his alleged role in helping Jagan in amassing wealth disproportionate to his known sources of his income, CBI sources said.
Prasad, who is alleged to have close links with Jagan, has also been arrested by the agency, they said.
The agency has already filed three charge sheets in connection with the case.
