This has been revealed by CBI in its over 10,000-page chargesheet filed earlier this month against Chavan and 12 others in the case.
The synopsis of the document mentions that Chavan had received Rs 70 lakh from Malav, son of his close confidant and builder Jayant Shah, as payment towards purchasing the flats for Chavan's relatives in the 31-storey building in South Mumbai.
"Out of the said amount, Rs 55 lakh and Rs 14 lakh were returned by Chavan after a PIL was filed on November 19, 2010, seeking direction to the Income Tax department and Enforcement Directorate to look into transactions and mode of payment made by members to purchase flats in the society," the chargesheet reads.
Chavan's mother-in-law Bhagvati Sharma and his father-in- law's brother Madanlal Milkhiram Sharma owned flats in the tower.
