Neymar testified to Brazilian prosecutors for five hours on Thursday in the wake of rape allegations made by a 26-year-old woman.
Najila Trindade accused the Paris Saint-Germain star of raping her in a Paris hotel, calling the May 15 incident "an assault together with rape".
The winger has vehemently denied the allegations levied against him, and has not been charged with any crime by Brazilian authorities.
On Thursday, Neymar provided testimony to Sao Paulo authorities for five hours before making a statement to the press.
"I will be brief... I just want to thank the support and care from all those who had sent me messages," Neymar said.
"And to say that I am calm. The truth will appear, sooner or later. The only wish I have right now is that this case ends as fast as possible".
Before Neymar's statement, the three prosecutors who interrogated him also made a brief statement of their own - in Portuguese - to the local media.
"He answered all the questions. From now on, the commissioner Juliana Bussacos will take the other actions needed to conclude the investigation.
"As the inquiry is confidential, we cannot say anything about these actions. He answered all the questions in a satisfactory way. He denied the crime."
After testifying for that investigation at the Virtual Crimes precinct on Thursday, Neymar thanked fans for their support while his lawyer, Maira Fernandes, claims to be confident her client will be found innocent.
Brazil are set to begin the Copa America on Friday against Bolivia.
