A Richmond star is under investigation over the distribution of explicit photos of a woman wearing his premiership medal.
The woman, who posed for the photos, alleges the images were then sent on without consent, police say.
"Yarra Crime Investigation Unit detectives are investigating an image distributed on social media," police said in a statement.
"The image was posted without consent.
"As the investigation is ongoing it would be inappropriate to comment further," they said in a statement.
Reports of the photos emerged late last week.
The images published by News Corp show a topless woman wearing the 2017 premiership medal and in another, she has her back to the camera and is holding a football in front of a wall with a Richmond logo on it.
Her face is not shown in either photo and the player whose medal she is wearing is also not identified.
The football club's president Peggy O'Neal appeared on ABC television's Q&A program on Monday night and was quizzed about the photos.
"I can't really comment on the particular event. I don't have all the facts about that," she said.
"But if it turns out that it is disrespectful to women, we certainly don't stand for that, that's not what our club's about, and if someone has made a disrespectful and humiliating gesture, then of course it will be taken into account."
Ms O'Neal said such incidents was not "what we're about" and Richmond had "shown it's for equality, it's for inclusiveness and it wants to promote women".
