Claiming passport back from the public prosecution

Hi Sir,

I had a case which was registered in Dubai and then transferred to Abu Dhabi Courts and settled.

I took bail from Dubai on my passport. Now, I am in search of my passport. Can you please advise what to do?

I have gone to different police stations including CID HQ but no one has the passport.

The CID HQ has given a copy of a letter from my case files in the system showing my passport is transferred to Abu Dhabi public prosecution in November 2018.

Whom should I contact in this regard?
