6/2 -- Neymar himself has responded to the rape allegation, posting a lengthy video on Instagram ... which he captioned in Portuguese ... "Because of extortion, I am being forced to expose my life and family." In the video, which is filmed in Portuguese, he says in part, "I'm being accused of rape. Yes, it is a heavy word, a very strong thing ... what happened was totally the opposite of what they are talking and saying," Neymar said. "I'm very upset at this moment."

He went on to show WhatsApp messages that he says were sent between himself and the woman in the days leading up to the alleged incident, which show multiple intimate photos being exchanged. It appears a few more messages were sent afterward as well.

6/1 4:41 PM PT -- Neymar's father and agent, Neymar dos Santos, has come out to call the rape allegation a "set-up." In a local television interview, Neymar's dad roughly said, "If public opinion is not cleared up, and if we can’t show the truth rapidly, this will snowball. If we have to show Neymar’s WhatsApp and the conversations with this girl, we will, because it is clear that it was a trap."

Brazilian soccer star Neymar has been accused of rape -- and the alleged victim has gone to authorities in Brazil to file a report ... according to multiple outlets.

AP says they've obtained a police report filed Friday in Sao Paulo, in which the unnamed woman claims to have been raped by Neymar on May 15 at a hotel in Paris. She alleges that after exchanging messages on Instagram, a representative for Neymar's soccer team -- Paris Saint-Germain F.C. -- bought her a plane ticket and booked her a room.

She reportedly went on to tell police that around 8 PM that night, Neymar came to the room seemingly drunk and had forceful sex with her.

Neymar's reps have not responded for comment at this point. He's currently in Brazil preparing the Copa America, which kicks off next week.
