Police in Rio de Janeiro have apprehended professional wrestlers Tajiri and The Great Muta under suspicion of tampering with the water in Olympic pools, which perplexingly turned green this week.

Tajiri and Muta deny any involvement, though they failed to explain why they are in Rio, and why green saliva was dribbling from their lips when they were arrested.

Asian wrestlers are well known for their ability to spew green mist when threatened — a bizarre biological adaptation that, according to one study, is universal to all Asian people.

Brazilian police are keeping mum about other possible suspects in the pool discoloring, but witnesses have reported seeing Killer Khan, Lord Tensai and Kendo Nagasaki near Olympic aquatic venues.
