The 26-year-old, along with two other men, were detained at a west London police station after a 34-year-old woman reported an alleged attack to Kent Police.
A police statement read: “Officers from Sapphire [unit] are investigating an allegation of rape which happened on 6 May in the west London area. The victim alleges she was raped by three men.
“On the morning of Wednesday 15 May three men, aged 26; aged 23; aged 22yrs, were arrested at an address in Fulham on suspicion of rape – they remain in custody at a west London police station.”
Relegated QPR, who signed Remy from French Ligue One side Marseille for a club record £8m in January, said they were unable to comment due to the ongoing police investigation.
