Two Paris St Germain fans were taken to hospital after being stabbed following Wednesday night's Champions League match against Barcelona at the Nou Camp, Catalan police have announced.
According to a statement by the Mossos d'Esquadra police force on Thursday morning, one of the fans remains in hospital after being attacked by two people wearing balaclavas while, soon after, another visiting supporter also suffered stab wounds but has already been discharged from hospital.
According to reports in Spain, the injuries suffered by the fan who is still in hospital are serious but not life threatening.
The incidents come just over a week after a Deportivo La Coruna fan was killed following violent clashes between rival groups before a Primera Division match between Atletico Madrid and Depor at the Vicente Calderon stadium.
A statement published on mossos.gencat.cat read: "Mossos d'Esquadra' police officers - from the criminal investigation division in Barcelona - are investigating the assault of two PSG fans following the Champions League match held in this city last night.
