On the construction of house at Saifai in Etawah, whose valuation was recommended, it was found that out of the total cost of Rs 1.41 crore incurred on it, the contribution of Yadav and his son was less than 10 per cent.
The house was constructed by Sughar Singh Yadav, head of the undivided family during the check period, the CBI said.
The agency also said that enquiry has not brought out any contribution of Yadav and his family members in the alleged benami properties in the name of Samajwadi Party and Ram Manohar Lohia Trust as mentioned by the petitioner Vishwasnath Chaturvedi in his plea before the Supreme Court.
The alleged stakes of Yadav and his family members in two educational institutions have been found not correct. The allegation of benami properties acquired by his wife Sadhna in the name of his son Prateek (who was a minor during the check period) have not been found to have any basis, CBI said.
During the present enquiry, it was found that an amount of Rs 51.85 lakh was earlier shown as income from loan in respect of Mulayam.
