Hamburg's Toni Leistner stormed into the stands to confront a supporter and push him to the floor following his side's German Cup defeat on Monday.
Dynamo Dresden romped to a 4-1 victory in front of a crowd of 10,053 - the biggest in Germany since March - before the former QPR defender found his inner Eric Dier by making his way up the stairs only to take it one stage further by actually attacking the fans he was pursuing.
Summer signing Leistner, who was born and raised in Dresden, pushed a fan in the chest and shoved him further to the steps while other supporters intervened to hold them back.
It's assumed the 30-year-old must have taken exception to some personal abuse although the exact reasons remain unclear. Reports in Germany claim it was a 'random' fan unknown to the player.
Back in March, Dier was said to have reacted the way he did after receiving verbal abuse in front of his family following an FA Cup defeat and was subsequently banned for four games and fined £40,000.
Leistner can expect a heavy penalty too.
