Hi,
You should contact a civil lawyer that is in the area of police corruption, and misconduct as it seems as though the criminal matter has been heard and determined.
You could possibly launch a civil action against the police and attain compensation as a result
A few points of interest could be malicious prosecution, perjury, police misconduct if an officer has acted unethically and also lied under oath along with misrepresentation of facts e.g. factual detail in brief was incorrect
I believe that even the police should be accountable for their actions
