New Delhi: In an embarrassing incident for the organisers, stray dogs bit coaches from Kenya and Japan in separate incidents during the World Para Athletics Championships here on Friday. Blood was oozing out of his leg and the medical team stationed at the stadium reached there. The organisers said both the coaches were immediately attended to and provided on-spot medical attention at the Athlete Medical Room. "Two on-site teams, supported by stationed vehicles, continue round-the-clock operations to ensure there is no compromise on participant safety and the successful hosting of the Championships." Since National Dope Testing Laboratory (NDTL) in Delhi is WADA accredited, the samples could be tested here, an official said.
