The Brazilian Olympic Committee is investigating a complaint of harassment from a member of their Paris 2024 team who was sent home from the Olympics.

Brazilian swimmer Ana Carolina Vieira was expelled from the Brazil delegation while teammate Gabriel Santos was given a warning after they allegedly left the athletes’ village without permission.

The infraction reportedly came to light through their social media activity with the BOC claiming the swimmers had ‘committed acts of indiscipline’.

Vieira was also accused of challenging the formation of the relay team she was a part of in their opening event on Saturday, earning a harsher punishment than her compatriot.

But in video shared on social media, Vieira has denied any wrongdoing, also alleging she filed a complaint of harassment with the COB she claims was ignored.

Vieira also claims she left the athlete’s village without getting the chance to gather her belongings, travelling to Portugal before heading back to Sao Paulo.

“I left there and left my materials, I didn’t know what to do,’ Vieira said.

‘My things are there [in the Olympic Village], I went to the airport in shorts. I had to open my suitcase at the airport. I’m in Portugal, I’m going to Recife and then to São Paulo.

‘I am helpless, I have had no access to anything, I have not been able to speak to anyone. They told me to contact the COB channels. But how am I going to get in touch?

‘I have already filed a complaint of harassment and nothing has been resolved, harassment within the team.

She continued: ‘I will speak to my lawyers. I promise to tell everything. I am sad, nervous, but with a peace of mind because I know who I am, I know what my character and my nature are.

‘I hope to be able to defend Brazilian women’s swimming with great pride. I ask for patience, thank you.’

According to Brazilian outlet UOL, the COB is now investigating the existence of the complaint of harassment.
