United spokeswoman said: “We have liaised with Northumbria Police and the matter is now in their hands.
"We have a zero tolerance approach to racism and will always seek to take the strongest possible action.”
A police spokesman: “We have received a report of racist comments made on Facebook on which we’re working closely with Newcastle United.
"Northumbria Police take all reports of racist abuse very seriously and inquiries are being conducted.”
Show Racism The Red Card Chief executive Ged Grebby: “The use of Facebook and social media to bully and racially abuse people is not something that’s confined to people like Shola and Stan Collymore. It’s something that’s going on day in, day out.
“The club are very proactive in promoting their zero-tolerance approach to racism.
“Racism is still a huge problem in society, it’s not something we believe has gone away and Twitter and other social media is a new form of it.
"Shola has been fantastic in terms of our campaign ever since he started at the club. He’s been a great ambassador for Show Racism The Red Card and introduced Jermain Jenas and Olivier Bernard to us.
"He’s been a very important part of our work and I’m sure he’ll be wanting to see prosecutions.
“As soon as you put something into print in any form then you become liable for prosecution and we would expect the authorities to act strongly.”
Facebook: “It is against Facebook’s terms and conditions for users to post hateful content.
"Facebook is highly self-regulating, and we encourage people to report content that they find offensive or questionable via the reporting links on every page of our site.”
