False agreement of sale on an income tax attached property

A flat owner made an agreement of sale with me by taking token amount. Later when I approached for actual registration of flat, he revealed that the property is attached by IT department under sub section 1 of section 222 IT ACT 1962. IT department order has been issued much before I made the agreement of sale. He did not tell that the property is attached by Income tax department and taken the token amount for this expenses. Now he is not in a position to repay the token amount taken from me and also the amount due for IT department. What should I do in this case. Does income tax act section 1 of section 222 IT ACT 1962 punish the owner as he was violated the law. Is here any other criminal law which can punish.
