Diving pool mysteriously turns green

Pictures of the Maria Lenk Aquatics Centre diving well has led to a mass of internet speculation as to the causes of a sudden change in colour.

China's Chen Ruolin shrugged off an inexplicably green Rio diving pool to tie team-mate Wu Minxia's two-day-old record of five career diving gold medals on Tuesday.

China's magnificent divers stayed unbeaten in the Olympics as Chen and Liu Huixia won the women's 10m synchronised competition, taking China to three-for-three in its bid for an unprecedented eight-event sweep

But much of the attention at the event was directed at the Maria Lenk Aquatics Centre diving well's bizarre transformation from light-blue the day before to a murky green, the latest embarrassing hiccup for the Rio Games.

Venue spokesman Simon Langford said water tests found "no risk whatsoever to athletes' health."

"We are investigating to determine what the cause of the situation was, but we are happy to report that the competition was successfully concluded," he said

Chen and other divers said the green water was not a factor.

"I don't think this affected us in any way," Chen said.

British star Tom Daley, who took bronze in Monday's event with Daniel Goodfellow, was one of those who looked askance at the green water.

Rio's official Twitter handle said there're no risks for the athletes.
