Celtic F.C. supporter group the Green Brigade have gathered in Glasgow with the group putting on a display for their 15th anniversary.

Dozens from the group could be seen setting flares on Victoria Bridge over the River Clyde on Saturday afternoon. 

A huge banner was draped over the bridge emblazoned with the group's name, reports our sister title The Herald. 

Brodie from Donohoe Media who was standing by Victoria Bridge at the time, said: "The street wasn't closed and there wasn't any police escort. 

"They just dropped their banner, started chanting and set off their flares - it was thick, coloured smoke. 

"It only lasted five minutes and when the flares stopped they threw them in the river and left."

The Green Brigade posted a video on their Instagram account on Saturday afternoon showing members also marking the anniversary last night at George Square. 

It included the Celtic fans producing a pyro display as well as setting off fireworks and flares in the city centre at around midnight. 

Many took to social media complaining about the display and the disturbance is caused in the city centre in the early hours. 

The Green Brigade are situated in the North Curve corner section of Celtic Park.

Over the years they have been involved in many displays and several incidents and they have clashed with the club. 

A Police Scotland spokesperson said: "Around 50 people gathered peacefully on the Victoria Bridge in Glasgow around 12.45pm on Saturday, 17 July as part of a celebration.

"Those who attended adhered to social distancing measures and followed advice of officers,  before dispersing a short time later."
