I am working as Sub Inspector of Police in Law and Order department where in I would like to change into Anti corruption bureau. Can somebody help me writing a pleasing request to my higher officials.

You seem to like short cuts https://www.askmehelpdesk.com/workin...tml#post367228

Owing to your line of work, it would not be completely honest if we helped you write this request. I think this is one you must do yourself, in your own words in order to be up front. After all, it is anti corruption bureau you are trying to get a transfer to.
