More reports emerging from the case reveal that the goalkeeper tried to arrange the girl, who is a prostitute, for five Manchester United players.
But the goalkeeper has denied knowledge of the allegations calling them 'all lies'
"I am the first one to be surprised by this report. I deny it, it is false and nothing more, it is a lie and false," de Gea told a press conference at Spain's Euro 2016 training base.
"It is false what is coming out in the press and it will be in the hands of my lawyers," he added.
The girl claims she was forced into prostitution and she was taken to a Madrid hotel and introduced to another girl and two footballers.
Once in a room with the other girl, the witness known in police interview papers as TP3 said that she was told by Torbe that she had to comply with the sexual demands of the two Under-21 internationals (Muniain and Isco).
When she said she did not wish to have such kind of sex, she claimed to police that Torbe "grabbed her forcefully by the arm".
The witness said she had told Torbe in front of the footballers that she did not want to take part in the sexual encounter.
El Diario, who broke the news, claimed the players said they did not want any recordings of the encounter to be made in case their playing careers were affected.
According to the girl, the whole encounter was arranged by David De Gea.
