Firstly mate, think you might have been fobbed off if you wanted a result from the Police. The first occasion after you told her to stop would/should have resulted in a first instance harassment warning. Anything after would be arrest/summons, as the course of conduct has not ceased. For them to have a large file shows they are doing nothing with it. It doesn't matter if it's three emails or a hundred, the offence is complete. This legislation isn't new. Malicious communications is different, and again, is not new legislation. Threatening you over email etc is not an assault, it's malicious comms at best. If things have stopped for you, that's good, but if not, get back onto them and ask what the f*ck is going on. Hope this helps...
