BCCI secretary N Srinivasan had written a letter to Modi asking to return the missing documents to BCCI CAO Ratnakar Shetty and Modi has agreed to do that, a television channel claimed.
Shetty has been authorised by BCCI to look for the missing documents.
In his reply dated April 28, Modi said that he was ready to share the documents with the BCCI but the Board must "depute a person duly authorised by interim IPL chairman Chirayu Amin [ Images ]", according to Headlines Today.
"Please further note that the person should be authorized to give proof of receipt for all the documents.
"I would also like to put on record that the copy of all the documents duly authenticated would be retained by me and your person would be required to countersign the same so that there is no controversy in the future," wrote Modi, who was suspended on April 25 after the IPL III final on charges of financial irregularities in the running the league.
Srinivasan had written to Modi to return the documents, as they are the property of BCCI.
"These documents are the property of the BCCI and are urgently required in connection with investigation into BCCI/IPL affairs by the income tax and Directorate of Enforcement," said the letter.
"You are requested to immediately hand over all the documents relating to IPL that are in your possession to Prof Shetty, CAO, BCCI," the letter by Srinivasan said.
Shetty had said that BCCI did not have original copies of some documents relating to IPL, including those of losing franchise bids of inaugural auction in January 2008 and media rights with Multi Screen Media.
