Ask an Immigration Solicitor. Get an Answer ASAP.
First of all why was your application refused on 7 July 2017 and did you make this application with the help of a lawyer if not why not. What ongoing Police case. You should seek immediate legal advice. JustAnswer is not a place to receive legal advice.
You have not provided the exact reason the HO has given for the refusal. OK go back to your solicitor with this refusal. They are able to give legal advice.
