Greater Manchester Police has confirmed a Celtic fan was arrested in the build-up to Tuesday's clash with Manchester City... for throwing a hamburger at a horse.
The Glaswegian club headed into the final game of their Champions League group stage with fourth place guaranteed due to being unable to topple third-placed Borussia Monchengladbach.
Celtic AND City fans go mad for Roberts
But clearly at least one Celtic supporter let all the excitement go to his head and, according to police, assaulted one of their horses with a burger and then throwing a colossal tantrum in the van he'd been handcuffed in.
A tweet stated: "Celtic fan arrested for throwing a hamburger at a police horse in Piccadilly Gardens. Male started kicking about in the van! #nightinacell"
In the Group C match, Patrick Roberts - on loan at Celtic from Man City - put the visitors into the lead before Kelechi Iheanacho levelled for the hosts and the match finished 1-1.
Barcelona have topped the group ahead of Pep Guardiola's City side. Gladbach qualified for the Europa League last 32 with their third place ahead of Celtic, who picked up three draws and three defeats in the group.
