Two-time Olympic medallist Sushil Kumar was arrested by the Delhi Police on May 23 for his alleged involvement in the death of fellow wrestler Sagar Dhankar.
Kumar, 37, was arrested with his accomplice Ajay after being on the run from police for 18 days.
Police said that Sushil Kumar and his associates assaulted Sagar Dhankar and two of his friends on May 4 at Delhi's Chhatrasal Stadium. Dhankar later succumbed to his injuries.
The Delhi Police allege that Sushil Kumar wanted the assault to be recorded on video and shared "to establish his fear in the wrestling community," according to an NDTV report.
Police said that Dhankar and his friends were staying at a house linked to Sushil Kumar and were asked to vacate it which led to the brawl.
Sushil Kumar had earlier distanced himself from the fight claiming that outsiders had jumped into the premises and beat up Sagar. However, the Delhi public prosecutor revealed that electronic evidence showed Sushil Kumar's involvement.
Sushil Kumar won a bronze medal at the 2008 Beijing Olympics and a silver at the 2012 London Olympics to become the first Indian individual athlete to medal at two different Olympic Games.
Sushil Kumar became a World Champion in 2010 and also won five gold medals at the Commonwealth Games. The 37-year-old is also a recipient of the Arjuna Award, Rajiv Gandhi Khel Ratna award and the Padma Shri.
Despite being ignored for the qualifiers for the Tokyo Olympics, Sushil Kumar has been practising to make one final push to make the cut. He is currently employed with the Indian Railways and was posted as an Officer on Special Duty (OSD) at Chhattrasal Stadium.
