Ghosh was also brought along with the raiding team. Sources said the police seized a hard disk of a computer from Ghosh's home where the raid began early in the morning and continued for over an hour.
Ghosh, the CEO of Saradha Group's media arm, was charged under sections 420 (cheating), 406 (criminal breach of trust) and 120B (conspiracy) of the IPC. The Rajya Sabha MP would be produced before a court in Bidhannagar today.

Meanwhile, police were inquiring how Ghosh had made a Facebook post last evening when he was already arrested, the sources said.
They found that one of his friends and the input editor of his new channel were involved in putting the post on the social networking site.
The two were being interrogated by the police, the sources said. In that post, Ghosh termed his arrest as a "conspiracy" and said the police should take the help of West Bengal Chief Minister Mamata Banerjee and two other Trinamool Congress leaders to find the truth behind the case.
He also demanded that the chitfund scam probe should be handed over to the CBI immediately. Ghosh, who was once known to have a close rapport with party supremo Mamata Banerjee, was leading a tirade against the party after his name cropped up in the case.
TMC suspended him for anti-party activities in September after he made unsavoury remarks against it.
