This post should have been put up much earlier before you applied for another job while being in Govt service.
NOC is mandatory for such applications.
What did you write in the application for the current job in Arunachal Pradesh.surely you must have concealed your earlier continuing employment in MES.
Your discreetly sound out your administrative officer to find out procedure for exit from MES.
Running away or abandoning a Govt job and going to another Govt job has its own dangers.Your previous employment and abandonment thereof will be found out.
This is a call which you have to take.
