Responding to an anonymous tip-off received by election officials, the joint team surveyed the hotel where Meetha Lal Jain, a former MP (12th Lok Sabha) from the Pali parliamentary constituency, was putting up.
"Jain is being asked to disclose the source of the cash," a senior IT official said.
"We are yet to seize the cash and and are asking him to supply valid statements pertaining to it," the official added.
