Newcastle United defender James Perch has been a victim of racial abuse on Twitter.
The 26-year-old was targeted after a clash with Liverpool goalkeeper Pepe Reina resulted in the latter receiving a red card during Newcastle's 2-0 win over the Reds on Sunday.
A twitter user, understood to be a Liverpool fan, is reported to have tweeted: "I want to punch perch in his n***** head!"
A Durham Police spokesman said: "Northumbria Police contacted us yesterday afternoon after a member of the public complained about allegedly racist comments posted on Twitter.
"As the complainant lives in County Durham the matter was referred to Durham Constabulary and an appointment has been made for an officer to visit them and take further details."
A police investigation is underway.
