England football fans' moronic behaviour in Germany included singing an obscene song mocking the Pope, as well as Stormont deputy first minister and former IRA commander Martin McGuinness on the day he died.
Footage of the chanting in a packed Dortmund pub has been posted on YouTube, which should make it easier for the authorities to identify culprits and take the necessary action.
The incessant chant went: 'Martin McGuinness, he died this morning, The England boys are off to Dortmund, Celebrating the only way, **** the Pope and the IRA.'
The anti-social conduct continued during the game, when the amount of beer thrown by England fans from the upper tiers on to their compatriots below is said to have made the lower stand look like it had been flooded.
