cheque related issue

I gave my friend some amount to start business but he cheated me by using that amount in his personal debts now when I asked him to return my money he gave me a cheque which was bounce so I filed case on him and case status is showing summon stage .here my question is I came to know he is abscanding and know one knows where he is. he is hiding because he is debt to many other people and he also changed his present address from previous which I was aware. now how my case runs as it's difficult to serve summon on previous address
