Police Scotland are investigating a complaint of racist chants against Rangers' Alfredo Morelos in Sunday's Scottish Premiership win over Celtic.

The Ibrox club said on Monday that they believed the Colombian striker was targeted during the 2-1 victory.

Police also confirmed "offensive social media material" is also being probed and that enquiries are ongoing.

Morelos, 23, was sent off near the end of the derby after being shown a second yellow card for diving.

Celtic said on Monday they had not received any reports of racial abuse but would "fully investigate any should these be brought to our attention".

Rangers' victory moved them to within two points of league leaders Celtic, with a game in hand to play in the new year.

Morelos was pictured drawing a hand across his neck in an apparent throat-cutting gesture as he left the field following his dismissal.

Celtic said they were "aware of the gestures made by the player towards Celtic supporters".
