Yesterday Dundee chief executive John Nelms said “We refer the matter to the league.
“They will be informed this morning and we will wait and see what actions they will take.
“There is no place in football for actions like that.”
A spokesman for Dundee United said “Dundee United FC are fully supportive of Nadir Ciftci in relation to allegations reportedly made against him by a Dundee player in the 3-0 derby win on Sunday at Tannadice.
“The Club has interviewed Nadir today as the accusation levelled against him is very serious and Dundee United would not condone such behaviour”
