Sevilla’s first team were forced to spend the night at their training facility on Saturday evening after they were met with “violent attacks” by supporters.
A statement released by the club strongly condemned “organised vandalism” at the Jose Ramon Cisneros Palacios training complex after Sevilla’s 3-2 loss at 10-man Celta Vigo.
Footage on social media appears to show a large group of supporters chanting outside of the facility with pyrotechnics, while another shows them tearing down the gate to the entrance of the training ground.
Players and staff of the La Liga side were forced to stay inside the building following their arrival back from Vigo.
Sevilla added that the club “will pursue the public naming of employees and the dissemination of private data on social media and in the media, acts that constitute criminal offenses”.
Defeat in Vigo left Sevilla 16th in La Liga, six points above the relegation zone with three games left to play.
