Espanyol has been reported to Spain's anti-violence commission following alleged incidents of abuse from fans against Barcelona.
La Liga's governing body has called for Espanyol fans to be punished for alleged homophobic and racist abuse during last Saturday's 2-0 loss to city rival Barcelona.
The National Professional Football League (LFP) sent officials to monitor crowd behavior at the fixture, from which away fans have been banned due to trouble at previous games, at Cornella-El Prat.
And it has now issued a complaint to the Spanish government's anti-violence commission.
According to the LFP, home fans directed monkey noises towards Barca's Neymar and Dani Alves, chanted a homophobic song in the direction of Gerard Pique and insulted Jordi Alba after he was sent off early in the second half.
