"Today, the ED officials have conducted a survey of the equipment lying at the studio of the TV channel which Shuvaprasanna owned and proposed to launch and then sold it to Saradha Group chief Sudipto Sen," a top source in the ED told PTI.
Earlier, the ED officials had questioned the painter, considered close to the ruling Trinamool Congress, in connection with the scam.
The CBI also interrogated him for the same reason.
