Kolkata, June 1 (IANS): A city branch of a nationalised bank on Monday furnished to the CBI documents giving details of several accounts West Bengal's ruling Trinamool Congress maintains with it.

The Central Bureau of Investigation (CBI), probing the multi-crore-rupee Saradha scam, last week sent notice to the bank seeking details of the accounts, including the quantum of funds maintained in these accounts as well the sources from which they came.

In pursuance of the notice, an official of the bank on Monday furnished the required details.

"Today an official of the bank submitted documents related to the accounts," said a CBI official.

The Trinamool in April had furnished details of the party's accounts since 2010 to the CBI after the agency sought the relevant details.

Opposition parties -- CPI-M, BJP and the Congress -- have been accusing the state's ruling party of receiving unaccounted donations from unscrupulous sources.

The Trinamool accused the BJP-led central government of harassment.

"Big parties and leaders amass billions, little guys get the questions. Before questioning us, question yourselves and your daylight dacoity to fund your multi-billion-dollar election campaign. Trinamool accounts are transparent, nothing to hide," Trinamool Rajya Sabha member Derek O'Brien said on last week after the CBI notice was issued to the bank.
