Ghana winger Christopher Antwi-Adjei was subjected to racist abuse during Schalke 04’s DFB-Pokal first-round clash against Lokomotive Leipzig on Sunday.

The incident occurred in the 13th minute when the 31-year-old moved to the touchline to take a throw-in.

At least one home supporter is reported to have directed racist insults at him, prompting the referee to halt play briefly for a stadium announcement.

Instead of support, sections of the home crowd booed Antwi-Adjei every time he touched the ball until the final whistle, a reaction Schalke described as “utterly incomprehensible and disappointing.”

The player later filed a complaint with police, who have opened investigations.

“It is very disappointing to still have to experience something like this today. It should not happen. I hope this person thinks again about their words," Antwi-Adjei said.

Schalke’s sporting director Frank Baumann said: 'We condemn this behaviour in the strongest terms and hope the perpetrator will be identified. Schalke stands firmly at Christopher’s side.'

Head coach Miron Muslic stressed the seriousness of the incident, saying: “We cannot just put this aside. The entire stadium sensed what happened, yet they booed him. That is not the act of one individual.”

Schalke reaffirmed its long-standing commitment to fighting racism and promoting tolerance.
