Diallo’s arrest came after she was named as a starter in the Champions League group stage match against Real Madrid on Tuesday.
The two midfielders reportedly have a long-standing friendship and have been snapped together during group holidays. The duo vacationed in Dubai together last December — Diallo uploaded a photo of them and fellow French international Aissatou Tounkara on Instagram, along with the hashtags ‘#sista’, ‘#goodvibes’, and #lafamilia’.
The 26-year-old joined PSG in 2016 and has made more than 60 appearances for the outfit. Diallo has also featured in every match for the Parisians so far this season and has played alongside Hamraoui in midfield on several occasions.
No charges have been pressed against Diallo or indeed an unnamed man, who was also arrested in connection with the attack. Both were in police custody on Wednesday.
PSG had also issued bodyguards to five of their players in the days prior to the attack on Hamraoui. According to L’Equipe, the women were receiving threatening phone calls from the same man, who is allegedly a childhood friend of Diallo’s and claimed he had an affair with Hamraoui during her time in Barcelona.
Police have suspected the calls made were an attempt to cover up the attack that would take place on November 4th.
Hamraoui has been assigned security both inside and outside her home after the events.
