All 518 Olympic doping tests return negative
All 518 doping tests carried out on athletes in aquatic events at the London 2012 Olympics returned negative, the sport's governing body Fina said on Sunday.
The Fina said ahead of next week's short course world championships in Istanbul that Olympic athletes from pool, open water and synchronised swimming, diving and water polo underwent 433 urine tests and 85 blood tests.
"All the tests carried out in the five aquatic disciplines at the 2012 Olympic Games were negative," Fina said.
