UEFA charges French champions PSG and Serbian champions RED STAR
The disciplinary panel will judge “crowd disturbances” against both clubs on October 18.
Red Star have also been charged for “illicit chants” inside Parc des Princes on Wednesday, though the club was banned by UEFA from selling tickets to its fans.
Rival fans clashed outside the stadium after PSG won 6-1.
UEFA also charged PSG because fans lit fireworks inside the stadium and has already punished Red Star this season for fan incidents including racist behaviour and damaging a rival team’s stadium in the qualifying rounds.
The Serbian champions are also under threat of a UEFA probationary order to close their stadium for a home game.
