Here's the alleged threat:

"I am going to locate you, disable you using either a quick 22 calibre to your lower spine and then duck tape and plastic shrink raps [sic]. Then I am going to kidnap you and take you to my secret hiding place.

"There I will castrate you and remove your penis using crude gardening tools, I will use a lightweight torch to cauterize your wounds and you will be awake and conscious during the entire procedure.

"Then I am going to prepare your genitals into some kind of meat loaf dish and use a nastro-gastric tube to force the fetid stew I have made from your genitals down your throat. Then I am going to cut into the left side of your brain using a power drill and an ice pick and I am going to study enough neuro-surgery that I have a good chance of making you aphasic so that you feel every bit of pain and terror I am going to inflict on you.

"Then I am going to use a blow torch to burn your skin off a little at a time until I am certain that you are close enough to death that and that [sic] the Burn unit and the Neuro-surgery unit has a medium chance to save your life.
