my wife filed a case under 138 n.i. act and 420 ipc as she had received a cheque which was returned on the ground 'Refer to drawer-A/c Frozen'. now the accused is threatning me to kill if my wife will not take back these two cases. two days ago, he assaulted me in the road infrontof 20 people and if people will not come out to rescue me then mostprobably i was a dead man by this time. i need police protection immediately. can i approach the metropolitan magistrate first class or should i approach the high court? thanks
