Official sources said a team of the Directorate visited the house Jain in New Friends Colony area.
They said the ED team may also visit some other locations where the CBI was conducting searches. The CBI was carrying out raids in Tamil Nadu and Delhi.
The sources said Jain's name had figured during investigations into the 2G scam and that the Directorate has found that Mahesh and his brother Alok Jain alias Bobby had allegedly registered companies as fronts.
CBI sleuths searched the office and residential premises of corporate lobbyist Niira Radia, former TRAI Chairman Pradip Baijal and a Chennai NGO with which DMK MP Kanimozhi is linked in a crackdown here and in several places in Tamil Nadu in connection with the scam.
Radia was earlier questioned by ED in connection with its probe.
