Make a police report, get the police down to interview them,
most likely the boss will sack you, but with the police report, go
MOM to complain about the unethical practice, then MOM will call in
the boss and you to drink coffee at Havelock road. MOM will advice
an outside settlement which the boss will most like agree, if not
MOM will enagage a Officer for you to file your case to the labour

Going to court need evidence and witnesses, you must have proofs
and witnesses, if not, just by your words, it is very easy for your
boss to twist and turn, if you have recorded the incident in your
h/p, that might had help alot
