NHS, Telephone Threat

Leicester police have told me the phone call made on the 31st December 2010 threatening my life was made from a telephone belonging to the NHS in Leicester.  Last night in a private council meeting ### tried to blame me for #### levels of stress. I don't have any proof that the call was made by anyone who works with #### or is known by ##### but isn't it a coincidence that a random stranger should threaten me from ###### place of work? I ask why would an NHS employee be so interested in my blog and the content relating to Oakham Town Council and then want to threaten my safety?
