Is there a way to hasten the results of bad deeds The law of cause and effect is unchangeable and we must face the consequences of the Karmas done through body, speech and mind. 

However, is it possible to hasten the manifestation of the results of bad deeds so that we can face them and be free. Is there any sutta or any practise that anyone knows that we can do to achieve this?

Only the five heinous crimes are guaranteed to manifest their results. According to what I have been told, others need a suitable environment/conditions to manifest at percent/future. But this is not entirely in your control.

Ex:- If you have in the past get involved in fights and beat up people, you would build up karma to eventually get beaten up in a fight. Because it is only natural and fully inline with dependent arising that you will over time keep increasing your abrasive nature and eventually meet your match. However if you stop getting involved in fights, that probability will be greatly reduced. But it is possible that someone from the past who held a grudge against you, plot revenge against you and succeed at a moment that you are weak.
