In February 2006, Celtic goalkeeper Artur Boruc was cautioned by the police for gestures he made to Rangers supporters during a match at Ibrox; six months later, it was clarified that this was for "Conduct which appears to incite disorder" rather than simply making the sign of the cross as he entered his area, as some had thought.[69] He also blessed himself in the fixture in December of that year, annoying Rangers fans who saw it as a provocative act, although the police stated that no offence had been committed.[70] Boruc, who became known as the 'Holy Goalie' for his overt displays of his Catholic faith, escaped personal punishment in 2008 for displaying a t-shirt with the slogan "God bless the Pope" and an image of fellow Pole Pope John Paul II after an Old Firm win at Parkhead in April 2008, although Celtic faced scrutiny from FIFA as it was an unauthorised garment under their regulations on slogans.[71][72] He was fined £500 and warned for (non-religious) gestures made towards Rangers fans in a defeat at the same venue in September of the same year.[73][74] Prior to an international match between Northern Ireland and Poland in 2009, graffiti of a threatening nature mentioning Boruc appeared on walls in a Rangers-supporting area of Belfast.[75]
