US gold medal swimmer Ryan Lochte was robbed in a taxi hold-up in Rio de Janeiro after leaving a party.
She did tell USA Today that her son was out with at least one US teammate in a cab heading to meet up with Brazilian swimmer Thiago Pereira when their cab stopped for gas.
"I'm just glad they're safe", she said.
Lochte confirmed details of the incident to NBC's Billy Bush, saying his vehicle was sideswiped and was held up by men with badges.
Additionally, an official in Rio says that they were aware of the incident but did not have any more information on what went down.
International Olympic Committee spokesman Mark Adams called the report "absolutely not true" earlier on Sunday.
The mother of Ryan Lochte has told two media outlets that the star swimmer was robbed at gunpoint in Rio de Janeiro while out celebrating the end of the swimming events at the 2016 Rio Olympics.
Australian Chef de Mission Kitty Chiller said the country's swimmers - now free to sight-see after completion of their competition - were among the Aussie delegation that have been instructed to take extra precautions when outside secure Olympic areas.
The four swimmers were leaving the French team's hospitality house, and got into a taxi to return to the athlete's village.
Ryan Lochte was part of the gold medal winning American 4x200 team here, and he has faced an array of challenges at past Summer Games.
Earlier, Lochte's mother Ileana told Fox Sports News 500 the 32-year-old rang her after the attack to tell her of the "terrifying" ordeal.
Ryan Lochte was unharmed but had his wallet taken, his mother told USA Today Sports. "He took our money, he took my wallet - he left my cell phone, he left my credentials". While Lochte is the world-record holder in the event, he registered a fifth-place finish in the IM in Rio.
