I-T sources said officials who were sent to collect documents and details of the transactions, share holding patterns and financial investments of the franchises yesterday, had finished their job and have also seized data from computers and other electronic peripherals.
The survey operations against the Pune team was conducted at Pune, Mumbai and Amby Valley at Lonavala near Mumbai while that against the Bangalore team was done in the southern city, they said.
A probe report in this regard was also sent to the Central Board of Direct Taxes (CBDT) headquartered in the national capital.
The I-T department is looking into the funding patterns for purchase of players by these franchises.
The surveys were being conducted in the wake of Pune Warriors' player Mohnish Mishra's statement that he had got much more than his prescribed auction amount under the table as black money during a 'sting' operation conducted by a news channel, which claimed to have exposed corruption in the IPL.
Mishra had later retracted his statement, saying he had said it casually "to develop his value".
