An Italian fan was arrested in Munich late on Monday for performing an Adolf Hitler salute after the police were called to a beer hall where a gathering of Lazio supporters had assembled.
Bayern Munich hosted Lazio in the second leg of their Champions League Round of 16 tie on Tuesday night.
In a statement on Tuesday, Munich police said that an 18-year-old was arrested for performing the salute and released after posting a four-figure sum as bail.
Italian media shared a video showing Lazio supporters congregating in a Munich beer hall, enthusiastically chanting 'Duce! Duce! Duce!' - a familiar term for the former Italian dictator and ally of Hitler, Benito Mussolini.
