Bristol City say they are investigating reports of racist abuse from their own fans during Saturday's defeat to Luton Town.
The club says its been "made aware" of racist language used in the away end at Kenilworth Road; City lost the match 3-0.
In a statement City's owner Steve Lansdown has condemned all forms of abuse and said the club will fully investigate.
He also says anyone found responsible will be banned from future games.
“I am shocked and disappointed to hear of these allegations," his statement reads.
“I can assure our genuine supporters and Luton Town, who have been very helpful, that we are fully investigating these reports.
"We will deal harshly with anyone found behaving in a racist manner and they will be banned from Ashton Gate and from purchasing tickets at future away matches.
“Racial intolerance is not something that we want being associated with our club in any shape or form.
"I firmly believe that, in no way is it representative of our true supporters or the essence of Bristol City as a family club which celebrates diversity and inclusivity.”
Two other games this weekend were also marred by allegations of racism.
Yeovil Town's FA Cup tie against Harringey Borough was abandoned following accusations the home side's goalkeeper Valery Douglas Pajetat was spat at and racially abused.
