Norwich confirmed on Monday they will probe reports of racial abuse by a handful of their supporters during Sunday's Championship defeat at Wolves.
The Carrow Road club received numerous complaints from fans following an incident in the visiting end as the Canaries lost 1-0 in their first competitive match after last season's relegation from the Premier League.
Norwich have passed the information on to police and stated any fan found to be guilty would face a lifetime ban from attending matches at Carrow Road.
A statement on the club's official website read: "Norwich City can confirm the club has received a number of complaints from its supporters about an incident in the away end at Molineux during Sunday's Championship match against Wolverhampton Wanderers.
"Following allegations of racist behaviour by two or three supporters, the club is passing our evidence on to police and asking them to investigate the matter further.
"In addition to and separate from the outcome of any police enquiries, the club will ban any supporters we are satisfied are guilty of racist behaviour from Carrow Road for life.
"The club has a zero-tolerance policy on racism and other forms of discrimination and will always ban anyone found guilty of such behaviour from our ground.
"The vast majority of our supporters are a credit to this football club and the county of Norfolk and we would like to thank the many Norwich fans present at the game who brought this matter to our attention and to the attention of the safety staff at Molineux so promptly."
