Rangers striker Nacho Novo is the subject of a police investigation following an incident at the end of his side's 1-0 defeat by Aberdeen. Novo was photographed with his shorts lowered beneath his buttocks as he walked off the Pittodrie pitch after Saturday's Clydesdale Bank Premier League match.
The 30-year-old could now face police action or disciplinary procedures from his club or the Scottish Football Association.
A Grampian Police spokeswoman said: "We can confirm we are investigating an incident involving a player at the end of the Aberdeen-Rangers match.
"As a procedure both clubs will be contacted and the appropriate action will be taken."
Rangers, whose defeat was their first in the SPL this season, declined to comment on the issue.
