Manchester City duo Leroy Sane and Ilkay Gundogan were both the target of racial abuse during Germany's 1-1 draw against Serbia during a friendly at the Volkswagen Arena in Wolfsburg on Wednesday.
The pair both started the friendly match, which saw Leon Goretzka's goal cancel out Serbia's opener from in-form forward Luka Jovic.
Sane was withdrawn late on in the match following a horror challenge from Serbia's Milan Pavkov, which saw the Red Star Belgrade man receive a straight red card.
According to reports in Germany picked up by the Manchester Evening News, the three individuals responsible for making the racial comments during the match have since turned themselves in to the German authorities.
An official statement from the German FA reads:
"Thanks to the support of a fan, the DFB was able to locate the ticket buyer for the seats where the spectators were sitting. The police have been turned on and are now investigating."
The incident in Wolfsburg sees the subject of racism involving the German national team thrust back into the spotlight, following Mesut Ozil's retirement from Die Mannschaft in July 2018.
The shock decision from the Arsenal midfielder to end his international career was clarified as he cited racism and disrespect from his own supporters over his Turkish dual-nationality as the main reason behind his decision.
