Valencia forward Rafa Mir has been arrested by the Spanish Civil Guard for alleged sexual assault, the club announced on Tuesday.
A spokesman for the Civil Guard confirmed that a LaLiga player has been arrested in Valencia for alleged sexual assault of a woman, but did not reveal the name.
Valencia said in a statement that he was aware of the arrest and would cooperate with the justice system. Representatives for Mir could not immediately be reached for comment.
The news was first reported by Cadena Ser, which said another person allegedly involved in the attack had also been arrested.
Sources close to the investigation told Spanish news agency EFE that a 25-year-old woman filed a complaint against Mir on Monday following an incident at the footballer's home.
The woman claims that she and her 21-year-old friend were sexually assaulted by Mir and another man at the residence.
Efe reported that the women were taken to hospital after the alleged attack and that so far the police have only arrested Mir and that the search for the second man is continuing.
Mir, 27, joined Valencia on loan from Sevilla this summer and has featured in all four of their LaLiga games so far this season.
The former Spain Under-21 international had started his senior career at Valencia and played for Wolves, Las Palmas, Nottingham Forest, Huesca and Sevilla before returning.
