The brawl at the Chhatrasal Stadium that allegedly led to the death of a former junior national wrestling champion was the result of a conspiracy hatched by Olympic medallist wrestler Sushil Kumar, who wanted to re-establish his supremacy among younger wrestlers, the Delhi Police has said in its charge sheet filed in the murder case.

There were "murmurs" that Kumar was scared of the two tenants living in a house he owned and he "nursed a deep grudge" about the loss of respect in the eyes of his students, it said.
