Advance money for Land

We received 2.5 lakh in cheque for selling our land, we didnt sign any documents for this, this cheque was give to us by a land broker(shekar), this cheque was signed by a person named Sriram and we deposited it in our bank account. (I repeat we didnt sign any documents) we waited for 4 months and since the broker was not showing interest for further payment, the broker(shekar) told us that we can cancel the deal, sriram never meet us, all the communication was through broker(shekar). We didn't cut any penalty also and returned the full amount of 250000 to shekar's( brokers) bank account, all the bank transactions receipts are available. now after 2 years sriram (whom we are speaking the first time) is saying shekar (broker) didnt return 2.5 lakh to him and is saying that his signed cheque came to our account. sriram and shekar had singed a cash receipt note amongst themselves which i managed to collect through some links. Can sriram file a police complain on us?or this is a civil case? its a clear case where shekar took the money of sriram.
