Scottish football cannot have “another season of this mayhem”, Chief Constable Jo Farrell has said, as she branded the behaviour of some fans at Celtic’s Premiership title victory “an embarrassment”.
Police Scotland have made 14 arrests after disorder at the title decider against Hearts, she said, stressing that inquiries are continuing.
Hundreds of Celtic fans streamed on to the pitch at Parkhead while the game was still being played, with thousands of supporters later descending on the Trongate area of Glasgow.
More than 900 police officers were called in to deal with the unrest, with two sustaining serious injuries.
Ms Farrell told Thursday’s Scottish Police Authority meeting that officers “came under prolonged and sustained attack” after the May 16 match, with some suffering injuries “including cuts and bruises from missiles”.
She said Police Scotland would “investigate and identify perpetrators” and there would be “consequences for those who involve themselves in this disgraceful behaviour”.
With the football season over, Ms Farrell added: “We cannot look towards another season of this mayhem.
“Policing will play our part with the football authorities, the clubs, the local authorities and the Scottish Government to achieve a solution that improves public safety and reduces disruption.”
Political leaders including First Minister John Swinney have condemned the behaviour of some fans.
The Chief Constable added on Thursday: “I want to be clear, this violence and disorder is to be condemned at every opportunity by everyone who cares about Scotland, Glasgow and football. It is an embarrassment.
“Club employees, ground staff, police officers should not be subject to violence in the course of their work.
“Communities, businesses and members of the public should not face violence, disruption and damage.”
She added that such behaviour “diverts finite public services, including policing, from other duties which could otherwise support communities and victims of crime”.
