Query in 138 NI ACT

Hello everyone, I had filed case against the accused of cheque bouncing in 2014, first bailable warrants been sent by court, then non bailable warrants but accused didn't appeared before the court. Its been sent on the address last known to me, the reply on summons are that accused don't live in that address anymore even though his parents are still living at that place. On last date court ordered for 82 and ask the local police station to act as per that. Now my question is that what if he don't appear on next date even? What will be the next step of court? What I can do to make him appear before court? Kindly suggest and help me. Thank you
