Police are hunting football fans involved in disorder outside Hampden Park on the morning of the Scottish League Cup final.
A large-scale disturbance unfolded outside the stadium around 8.50am on Sunday morning involving Rangers and Celtic supporters.
The force has said it is fortunate that no one was "seriously injured" in the violence that was directed at each other and also officers.

No arrests could be made at the time but an investigation has since been launched into the incident with officers now beginning the process of identifying those involved.
Prior to the game, fans from both sides were given pre-arranged access by the stadium operator to set up displays. Celtic fans were allowed in on Saturday while Rangers supporters went in on Sunday morning.
Stewards and police were in place at the stadium to facilitate the fans.
Detective Inspector Darren Munogee, who is leading the investigation, said: “Supporters intent on disorder clashed outside the stadium on and around Somerville Drive with police intervention required to prevent escalation and disperse both sets of supporters.
“Officers acted swiftly in challenging circumstances to deal with what amounted to totally unacceptable behaviour. It was fortunate that no one was seriously injured.
“Police Scotland will be writing to the football authorities and clubs with an expectation that they will review the circumstances and take appropriate action moving forward, we are committed to working with them in this regard.
“We are determined to identify those responsible and bring them to justice. We are asking anyone with information that can assist with our enquiries to get in touch.
"Anyone who can help officers with their investigation is asked to contact Police Scotland on 101, quoting incident number 0933 of Saturday, 26 February, 2023, or make a call anonymously to the charity Crimestoppers on 0800 555 111."
