REVELLERS attending Celtic's unofficial title party have breached warning signs to climb a historic Glasgow building.
Images from the scene show people on the top of the Mercat Cross roof as hundreds descend on the Glasgow Cross area of the city following Celtic's 1-1 draw against St Mirren at Parkhead.
Supporters announced they would be holding an unofficial title bash in the Trongate after Celtic's match with St Mirren.
It is understood that police officers are now standing on the roads surrounding the area.
Glasgow City Council have erected clear signs on the monument saying, "Danger Fragile Roof" and "Strictly no access". 
The damage caused to the building during a title party celebration by Celtic fans last year has cost the council tens of thousands of pounds.
Glasgow City Council revealed they are forking out £73,032 to repair Mercat Cross after 25,000 supporters gathered on May 19, last year to mark Brendan Rodgers' side lifting the Scottish Premiership trophy.
This architectural gem was built in the 1920s and served as a meeting point and visible reminder of the markets.
Meanwhile, others in attendance have been spotted climbing structures in the area.
With thousands expected to turn out, First Bus have yet to make an official statement, however, they had advised of "anticipated disruption", adding: "Disruption to our City Centre services is anticipated due to a Parade and an expected gathering. Some services will be diverted while others will regrettably be curtailed."
