Ghosh, the suspended Trinamool Congress Rajya Sabha MP, was arrested in November last year for his connections with the scam.
Sen, who was arrested in April last year after the Saradha bubble burst, met his former employee inside the lock up in a court in Bidhannagar, where both were produced for hearing of a case.
What transpired between the two is not known, but Ghosh was seen smiling while coming out of the court and getting in a police jeep.
Sen too, before his arrest in April, had blamed Ghosh, the former CEO of Saradha group's media arm, for pressurising him to sell his news Channel 'Channel 10' at a subsidised rate.
