A group of 90 people were denied entry to Celtic Park by police ahead of today's Old Firm clash.
Officers said the group, most of whom concealed their identity, were not granted entry to the East End stadium after refusing to be searched under the Section 60 powers.
The fans were banned from the match as cops believed they posed a 'threat to the safety of people within the stadium and the public due to possible possession of weapons and pyrotechnics'.
Following this, the group was contained by officers, however, pyrotechnics were disposed of and set off allegedly causing a fire, which 'endanger both the public and officers'.

All 90 people will be reported to the Procurator Fiscal in relation to contraventions of Section 60.
We reported how cops had been given greater stop-and-search powers for the match.
From 8am to 11.59pm today (Sunday, March 16), officers have been authorised to use powers provided under Section 60 of the Criminal Justice and Public Order Act 1994.
The powers will be in place in various parts of the East and West Ends, as well as the Southside of the city.
The legislation permits greater stop-and-search powers of pedestrians or those in cars, as well as allowing officers to require the removal of face coverings hiding people’s identities.
Meanwhile, as part of the wider policing operation, there was one arrest made at the match.
A 20-year-old man was arrested and charged for alleged police assault on approach to the stadium.
He has been released on an undertaking to appear in court at a later date.
A second man, aged 46, will also be reported to the Procurator Fiscal for allegedly being in possession of a pyrotechnic.
The match, at Parkhead, finished with Rangers scooping a 3 - 2 win.

Chief Superintendent Stevie Dolan, who led the policing operation, said: "Again, the vast majority of fans were simply there to enjoy the match and I would thank them for their good conduct.
"It was necessary to apply containment tactics to maintain public safety and deal effectively with those intent on disruption or non-compliance with relevant legislation, including powers under Section 60 of the Criminal Justice and Public Order Act 1994.
"As a result, some groups of supporters missed the game, but that was their choice.
"Our priority is and always will be the safety of fans in and around the stadium and the general public in the wider city.
"To support that, enforcement of Section 60 and other legislation was undertaken proportionately, with search powers being enacted in a targeted manner.
"Non-compliance with the Section 60 powers resulted in 90 people being reported to the Procurator Fiscal.
"Others have been arrested or reported for other offences, including the assault of a police officer.
"A significant number of pyrotechnics were seized or prevented from entering the stadium, which again demonstrates the disregard that some supporters have for the safety of others.
"We will continue to work with partners, including the clubs, to improve safety and order and to ensure that the sporting event is the real focus."
