The move comes after the CBI court issued summons to the YSR leader to appear before it on May 28.
A notice was sent by H Venkatesh, Superintendent of Police and chief investigating officer in the case, to Jaganmohan Reddy for his alleged involvement in the disproportionate assets case.
"These companies have been maintaining accounts with your bank and parked the ill-gotten proceeds of crime received from various sources under the guise of funds for conducting business," said H Venkatesh.
The CBI chargesheet includes the name of the representatives of Jagati publications and other infrastructure business associated to the YSR leader.
Meanwhile, Jaganmohan Reddy, who is campaigning in the Rayadurg constituency in Anantapur district for his party candidate for the upcoming by-elections, called the CBI action against him as "a daylight murder of democracy aimed at stifling my media units. Having failed to take me on politically, they are hatching a conspiracy against me."
