CELTIC have been fined just over £20,000 by UEFA for crowd offences in their home Champions League qualifier against Linfield.

The Scottish champions were fined €23,000 (£20,616) over charges of an “illicit banner” and “blocked stairways”.

Uefa said the first charge related to a banner portraying a person in a paramilitary uniform.

Celtic had already taken action themselves following their 4-0 win on July 19, condemning the banner display and closing a 900-capacity area of the safe-standing section of their stadium for the goalless third qualifying round first leg against Rosenborg on Wednesday.

The Parkhead club explained they were closing the “Green Brigade section’’ for two matches after “serious incidents of unsafe behaviour’’ at their previous two home games.

The ultras-style group had previously fallen foul of the club over pyrotechnics at the last home game of last season against Hearts.

Manager Brendan Rodgers described the “political element” of the banners as unacceptable and admitted he was “saddened” by the display, which featured his name aong words and imagery associated with the IRA. Uefa has now fined Celtic 11 times in less than six years over fan-behaviour issues ranging from pro-IRA chants to fireworks, crowd disturbances and illicit banners.

The European governing body also announced that proceedings over a separate kit infringement offence had been closed. That charge was a minor issue relating to the display of their sponsor’s logo on substitutes’ bibs, which is prohibited in Uefa’s regulations.

The disciplinary hearing came a week after striker Leigh Griffiths was banned for the Rosenborg first leg for “provoking supporters” after he tied a Celtic scarf to a goalpost at Windsor Park after his side’s 2-0 win.
