New Delhi-- Two-time Olympic medalist Sushil Kumar was arrested on Sunday in connection with the murder of a fellow Indian wrestler, according to Delhi police.
Both Kumar, 37, and a second man detained over the same offense later appeared in court, a Delhi police spokesman added, without giving details of potential charges.
Police have been given six days' custody of Kumar, according to CNN affiliate CNN-News18.
Delhi Police issued a look-out notice for Kumar after a May 4 brawl outside Delhi's Chhatrasal Stadium.
Three people were admitted to hospital after the incident and one of them, a former junior national champion, eventually succumbed to his injuries.
