Water in Olympic diving pool mysteriously turns green

RIO DE JANEIRO, Aug. 10 (UPI) -- Several Olympic competitors and spectators were baffled after the water in the diving pool mysteriously turned green.

Prior to the women's synchronised 10m platform event on Tuesday, United States men's diver David Boudia, who competed in the pool on Monday, shared a photo of the green water.

"Wait is someone playing a joke or are we celebrating St Patty's Day early here in Rio?" Boudia wrote.

The event continued as planned and Olympic officials shared an update stating that the athletes were not at risk and the cause was being investigated.

"The water quality at the Maria Lenk Aquatics Centre was tested and there were no risks for the athletes. We are investigating the cause," they wrote.
