He did say he was going to drown his overrated ass in the f*cking pool too. It's not really a death threat though, just ridiculous.
All that should happen is these trolls should have their IP's barred from Twitter. That's all they need to do. Giving arseholes the chance to try & act clever by taking the piss out of celebs on there is bad enough. Sadly a lot of people get their kicks from taking stabs at people on Twitter. Get a life ffs.
