THIS is the shocking moment a Rangers ultra threw a firework into a pub full of Celtic fans.
CCTV footage showed the moment Gallagher’s Bar near Glasgow’s St Enoch Square was attacked.
In the video, a group of Celtic fans were seen drinking in the boozer when they began to look outside the windows.
The door of the pub opens and a Rangers ultra wearing a Santa hat tries to walk into the pub but is punched in the face by a Celtic fan by the door.
More ultras then appear at the side of the pub and start banging on the windows
But the door of the pub opens again and a firework is thrown in.
Punters inside dive clear after the explosive is thrown inside and ends up under a table.
Others quickly move away as the fireworks continues to explode.
Bright red flashes can be seen from the table as smoke fills the pub.
The man who punched the ultra in the doorway then moves and picks up the firework before appearing to throw it outside from another door.
It came amid shameful scenes in the city centre as the Green Brigade and Union Bears clashed on nearby Argyle Street ahead of their Old Firm cup final at Hampden.
Screaming Christmas shoppers were forced to shelter inside stores as rival groups lobbed fireworks at each other.
Scores of Celtic ultras in green masks and Rangers casuals in blue masks and Santa hats were filmed running riot through the busy shopping street.
Police raced to the scene with patrol vans filmed tearing onto Argyle Street with lights and sirens blaring.
One officer was forced to use his baton to keep back the rampaging Celtic casuals.
In another shocking clip, the Rangers ultras clashed with cops in the city centre with one lout squaring off with a cop before punching a police van.
Missiles were lobbed at cops during the disgraceful scenes.
The violence saw police chiefs enforce rare “Section 60” powers, which allowed frontline cops to use tough stop and search powers – which includes the ability to force someone to remove any item being used to conceal their identity.
The Section 60 stop and search power was in force in various areas including the city centre and parts of the South Side, East End and into South Lanarkshire until 9pm.
Chief Superintendent Stevie Dolan said: “We have dealt with a number of incidents in Glasgow city centre today involving individuals engaging in disorder and violence across the city.
“The use of weapons or violence will not be tolerated and officers will take action where necessary to ensure safety.”
