Hamburg's former Dynamo Dresden defender Toni Leistner climbed into the stands to confront fans of his old club after his side's 4-1 German Cup defeat.

In a video widely shared on social media, the former QPR player, 30, pushes a Dresden fan and argues with others before returning to the pitch.

Leistner was waiting to do a television interview when the incident occurred.

About 10,000 fans watched the game in Dresden - the biggest attendance in Germany since the coronavirus lockdown.

The Dresden-born player, who played for his hometown club between 2010 and 2014, later said he had been insulted by a supporter.

Dynamo have since condemned the supporter allegedly involved, saying it is "shameful" Leistner had been offended by a fan of his "home club".

"We're looking for the person because we don't want to let this incident stand," the club tweeted.

"Thanks to 99.9% of all stadium visitors for your support."
