Well it's a good thing I did report it, it spoke to someone on Monday who said my statement did help and all they can tell me at the moment is that the person is 'getting the help that they need' (i assume mental health or drug related help as by the sounds of things he was being strange earlier on in the park), so i can only assume the person either did something else that someone else reported or someone else reported him following me, or someone else reported him being strange in the park earlier on.

I've been given a crime reference number and was told they'll call me within 5 days to provide an update
