Delhi coach Rajvir Singh lodged a protest, insisting that his ward Lalit Yadav was denied a win in the men's Sanshou 75kg quarterfinals against Manipur's Joy Singh Oinam owing to pressure from chief referee Dhiramani Singh, who also belongs to Manipur.
"Rules clearly state that only neutral referees can officiate but he being the chief referee interfered and ensured that our boy lost the bout. The proceedings were halted for nearly 40 minutes because we protested but to no avail," Rajvir said.
The Manipur contingent did not respond to the charge when contacted.
The north-eastern state has dominated the wushu competition so far at the Games with a haul of four gold and one silver medal.
