A Polish fan attending a match between Slask Wroclaw and Zaglebie Lubin was set on fire as he was waving a flare.
The supposed Zaglebie Lubin supporter had climbed on top of a gate with the flare when a steward approached him and appeared to fire tear gas in his direction.
The result was that—briefly—the fan went up in flames.
You can see it happen around 100 seconds into the video above—the fan is in the bottom left-hand corner on his own.
An amazing picture was captured by Sebastian Borowski of the Newspix agency (as reported by Eurosport):

Remarkably, according to reports—including this one from Daily Mirror—the fan was unhurt from the incident. You can see him scurry back into the crowd of away fans.
His side, however, went on to lose the game 1-0.
