Twitter arrest in UK: Hope it never comes to this here.

Dorset Police said early Tuesday that a 17-year-old man was arrested at a guest house in Weymouth "on suspicion of malicious communications" in relation to Twitter threats made against Daley.

If there were threats, he may have been arrested for that, as opposed to just insulting the guy. Maybe some DMs were involved? The tweet quoted in the article was hardly a threat, but that doesn't mean there weren't any.
