Two other Lok Sabha members Tapas Pal and Satabdi Roy, who had accompanied Ghosh at the event, too aired their grievances at the forum.
However, they were spared following a written apology to party chief and West Bengal chief minister Mamata Banerjee.
Ghosh, who earlier headed Saradha's media arm, has made several allegations against his party leaders over the last few days. He even claimed that "three Trinamool Lok Sabha members secretly met Congress chief Sonia Gandhi's political adviser Ahmed Patel at a tea party in Delhi".
He had also alleged that a Trinamool leader demanding his resignation on the scam had in the past asked for Rs.4 crore from Saradha boss Sudipta Sen.
