A police investigation has been launched after Green Brigade members gathered in Glasgow’s George Square to celebrate their 15th anniversary.
Scores of Celtic fans descended on the city centre street where they released fireworks and lit bright flares in the early hours of Saturday morning.
A video from the scene, taken from a hotel which overlooks the Square, shows the colourful explosions filling the sky before the group of supporters start running away.

Twitter account North Curve Celtic also shared a video of the supporter group with members spelling out ‘Green Brigade’ using their bodies and flares.
One eye witness who stumbled across the raucous display told how she initially heard what she thought were ‘gunshots’ before realising what was going on.
She said: “I honestly had no idea what was going on because I heard what I thought were gunshots.

“Then when I turned the corner, I saw the sky was just filled with flashing but couldn’t really see what was happening or if there were people involved.
“The area was so filled with smoke and then I noticed them all legging it away. It was really quite bizarre.”
Police Scotland have confirmed they received a report of a large group gathering shortly after midnight.
A force spokesperson said: “Officers received a report of a disturbance by a large group in George Square, Glasgow at 12.40am on Saturday, 17 July.”
