Twitter threat: "I'm going to find you and i'm going to drown you in the pool you cocky tw*t your a nobody people like you make me sick."

The 18-year old English diver was due for a huge outing at the 2012 Olympic Games in London, but failed to capture the gold in the synchronized diving competition. He tweeted about his loss and disappointment and caught hell from numerous followers, with one saying that Daley let his deceased father down. After some jabbing back and forth, the conversation took a disturbing turn when the troll threatened to murder the swimmer in a pool. Cold world.
