The bank's branch manager Pramod Sharma and cashier Rajender Sharma were arrested yesterday in this connection, SP (City) Raj Kamal Yadav said.
He also said that a hunt was on to nab Anil Verma, the main accused in the scam that took place during 2008-09.
A former district welfare officer, Rinku Singh Rahi, had alleged a multi-crore scam in the social welfare department by staging a dharna in Lucknow seeking reply to an RTI query in connection with the "scam".
The Samajwadi Party government had ordered a probe into Rahi's charges after coming to power in March this year.
