Union Berlin said on Wednesday that one of their supporters has been banned for anti-Semitic insults directed at visiting Maccabi Haifa fans during a match in Berlin.
"There is no tolerance whatsoever for discrimination at Union Berlin," club president Dirk Zingler said in a statement.
"We have therefore taken all measures available to us to remove this person from our ranks."
After Maccabi Haifa fans were insulted by certain home supporters during Union's 3-0 win in last Thursday's Europa Conference league match, the police and European football's regulatory body, UEFA, are both investigating.
According to the Union, a culprit has been identified and has been banned from all club property and matches for a "indefinite" period of time. Police have also been informed of their whereabouts.
The German Football Association has also issued a "national stadium ban" to the same individual by the Bundesliga club (DFB).
Zingler thanked Union fans for their assistance in identifying the culprit.
