These are the tweets from the Montreal Police:
For those who don’t know, Dennis Markuze is a perennial internet-only (so far) stalker who has been sending nasty emails and tweets to anyone he sees as a key Atheist figure or anyone thusly linked, and posting rambling often offensive sometimes threatening blog comments on our blog sites, for several years now. He is a Nostradamus cultist. A while back he was arrested and put by Montreal authorities into psychiatric care, and later released under certain conditions including that he not bother people on line any more. More recently he started up again with his old habits, the community of those he harasses complained again to the authorities, and he was, as you can see, re-apprehended.
