"No evidence" of racist comments being made at a Luton Town Football Club's match against Accrington Stanley has been found, the club has said.
Police are investigating two separate reports of remarks at the Kenilworth Road game on Tuesday one by a visiting journalist and one on social media.
The club said it had "listened carefully" to audio coverage from the home end and consulted supporters.
Police said they were working closely with the club on both of the matters.
In a statement, the club said one incident was reported to the club, police and stewards by a visiting journalist and, as a result, officials interviewed a number of supporters, invited others to comment and listened carefully to audio coverage.
The second incident developed from a social media post by a spectator in the away section, which accused Luton supporters of racist chants.
The club said that in both cases, it had "found no evidence to back up the accusations ".
"We would like to reiterate the club's stance that no form of discrimination is acceptable in football, or society as a whole, and with our stadium in one of the most racially and culturally diverse areas of the country, we pride ourselves on being good neighbours and hosts," the statement said.
"Any Luton Town supporter found to have made discriminatory comments will have sanctions imposed by the club and offered educational help on such an important issue."
Supt Nick Lyall said: "Bedfordshire Police and Luton Town Football Club work in partnership with Kick It Out and Show Racism The Red Card.
"Racism has absolutely no place in society, and football is no exception to that.
"Any allegations of racist behaviour are taken seriously, and will be investigated appropriately to ensure the sport is family-friendly and accessible to all."
