Six people were arrested as thousands of Celtic fans gathered in the streets of Glasgow to celebrate the club winning the Scottish Premiership title.
The Parkhead club lifted the trophy after a 6-0 home victory against Motherwell on the last day of the season.
Following the match, thousands of supporters gathered in Glasgow City Centre, with police launching a traffic warning for city centre routes.
It came after 5000 people responded to a Facebook page set up to promote a street party planned for the city’s Merchant City after the game.
Police Scotland said although there was an “unacceptable level of anti-social behaviour” there were no serious incidents or disorder.
Officers confirmed a total of six people were arrested and four were issued fines following the celebrations.
Chief superintendent Mark Sutherland, divisional commander for Greater Glasgow division, said: “Thousands of Celtic supporters gathered in the area of Glasgow Cross to celebrate their team’s achievement.
“A proportionate policing plan was in place which facilitated the gathering, prioritised public safety and sought to minimise disruption to businesses and communities.
“While there was an unacceptable level of anti-social behaviour and littering there were no serious incidents or disorder.
“There were some outbreaks of minor disorder and our officers acted swiftly and robustly to prevent escalation and protect safety.
“Over the course of the evening there were six arrests for offences including assault and acts of public disorder.
“A further four people were issued with fixed penalty notices.”
