London: Norwich City on Monday threatened a life ban for any fan found guilty of racism after the Premier League club`s manager Chris Hughton was the target of online abuse for the second time this month.
Police launched an investigation on Saturday after a number of supporters reported an offensive comment on an unofficial Facebook page.
Norwich were beaten 4-1 at Arsenal on Saturday and sit third bottom of the table with only two wins in eight matches.
It follows a similar incident earlier this month in which police said they were investigating a comment left on a social networking forum as a "hate crime".
The club said in a statement: "We can confirm that Norfolk police made us aware on Saturday of a new and separate incident of potential racist abuse aimed at Chris Hughton on an unofficial fans` Facebook page.
"As in the first and ongoing incident, we will co-operate fully with the police in their enquiries and we take it very seriously indeed, and if anyone is convicted of an offence in relation to these incidents, not only will they face whatever punishment is handed out by the courts, but they will also potentially face a life ban from Carrow Road from us."
