The doctor of suspended swimmer Park Tae-hwan was fined on Thursday for injecting a banned substance that eventually caused the Olympic gold medalist to fail a doping test.
  

The Seoul Central District Court ordered the doctor, a 46-year-old surnamed Kim, to pay a fine of 1 million won ($850) for failing to leave records of injecting Park with Nebido, which contains testosterone, a substance banned by the World Anti-Doping Agency.
  

The court said the doctor had failed to properly explain that the injection could lead to a positive doping test.
  

Still, the court found the doctor not guilty on the charge of professional negligence, saying there was no proof that Park had suffered bodily harm.
  

Park, who grabbed the gold in freestyle at the 2008 Beijing Olympics, failed a drug test last fall and is serving an 18-month suspension that ends in March next year.
  

The 26-year-old was barred from training at facilities operated by the government or by the national swimming federation, and has recently returned home from a training camp in Japan. (Yonhap)
