Former Paris St Germain women's midfielder Aminata Diallo has been placed under formal investigation and is being detained by police linked to an attack on one of her team-mates, the Versailles prosecutor's office said on Friday.

Diallo is being investigated on charges of serious bodily harm, the prosecutor's office said, adding that the player was being temporarily held as she awaits a court hearing about the pretrial detention.

Diallo's manager and lawyer did not immediately reply to a request for comment.

The case dates back to November, 2021 when PSG's Kheira Hamraoui was attacked by two masked men, who dragged her out of a car and assaulted her, local media reported. Diallo had been the driver of the car.

Hamraoui suffered serious injuries and needed hospital treatment but she later resumed playing for PSG.

Diallo, who has repeatedly denied her involvement, was questioned by French authorities after the incident but was released.

Four other suspects have been placed under investigation linked to the incident, the prosecutor's office said.

"All four alleged Diallo... was the instigator of the assault, in order to allow her to be given the place of the victim (in the PSG team) in future games," it added.

Le Parisien on Friday reported that prosecutors had closely monitored Diallo recently, including tapping her phone, on suspicion she and her accomplices could have been planning further action against Hamraoui, citing unnamed sources.

Diallo left PSG this year after the club ended negotiations to extend her contract.
