The sources said these 323 residential lines were allegedly in the name of BSNL General Manager connecting the Boat House residence of Maran with the office of Sun TV through a dedicated underground cable during his tenure as Telecom Minister.
The probe had started in 2011, nearly four years after getting complaints that a ‘virtual' telephone exchange was allegedly set-up at the then Telecom Minister's for facilitating data transfer from Sun TV.
The agency had recommended action to the then Telecom Secretary in 2007 but the department allegedly did not give its nod in the case, they said.
