Man City, Serbian defender Aleksandar Kolarov at center of police probe into racist language

Police are investigating an allegation of racist abuse following an altercation between Manchester City defender Aleksandar Kolarov and a Newcastle fan during a Premier League match Saturday.

Kolarov, who is Serbian, was warming up as a substitute when he is believed to have become involved in a lengthy exchange with a fan who was carrying an Albanian flag.

Northumbria Police say they have "received a report of racist language having been used at the St James' Park stadium," adding that "enquiries are ongoing into the incident."

There is a long history of tension between Serbia and Albania, particularly over the disputed region of Kosovo.

Kolarov came on as a 37th-minute substitute in City's 3-1 win.
