A Celtic supporter was arrested before his team's clash with Manchester City - for allegedly throwing a hamburger at a police horse.
Greater Manchester Police's city centre Twitter account revealed that the bizarre incident took place in Piccadilly Gardens ahead of the Champions League clash at the Etihad Stadium.
They added that the accused would be spending the night in a cell.
Around 4,000 supporters of Brendan Rodgers' side made their way south for the clash, with the majority well behaved.
