SAO PAULO (AP) — Brazil’s swimming federation says Olympic champion Cesar Cielo tested positive for a banned substance in May and will not be banned.
In a statement Friday, the federation says Cielo and three other swimmers tested positive for the diuretic furosemide at the Maria Lenk Trophy meet in Rio de Janeiro.
Furosemide is used to help lose weight and also can mask the presence of other banned drugs.
Cielo won the 50 meter freestyle at the 2008 Beijing Olympics.
The statement says the federation chose to give the four men a warning. The other swimmers are Nicholas Santos, Henrique Barbosa and Vinicius Waked.
Cielo also was stripped of the five gold medals and a silver he won at the Rio event. The other three swimmers lost a total of 12 medals.
