I live on Salcott Road and also run a business called Luv Handles the bike boutique in the area. OUr business premise is directly opposite the cemetery and there is in fact quite a bit of activity that passes through there after work hours. To shed light, I have seen activity to 'what appears' to be x1 first class drug dealing in my block of flats.
There was an increase of activity since Summer last year '2013 and I reported it to the police and a couple months later performed an investigation labelled "Operation Hawk" in the block. If you have any questions about this, I do suggest contacting them directly. The 'addicts' I have judged to be seen in this area all continue to go to this block in particular.
I suggest being aware that this type of crime is everywhere and to remember to not leave any opportunities visible and vulnerable to temptation in the event of.
So sorry to hear of these crimes
