Reports that American swimmer Ryan Lochte had been held up at gunpoint during a party in Rio were dismissed during a Sunday morning press briefing.
International Olympic Committee spokesman Mark Adams said that the reports were not true and that the response had come direct from Lochte via the United States Olympic Committee (USOC).
A USOC spokesman was unwilling to confirm any details when approached after the press briefing.
Earlier in the morning briefing, held jointly by the IOC and the Rio Olympic Games organising committee, Rio 2016 main spokesman Mario Andrada said: "We just had a quick report that there was an issue with him (Lochte) but we didn't have the detail that he was held at gunpoint."
Lochte was part of the US team that won 4x200 metres gold in Rio, taking his total number of Olympic medals to 12.
