Rockingham football club will be asked to “please explain” after one of its supporters donned a Ku Klux Klan outfit to watch a game in Pinjarra on the weekend.
A photo sent to the Mandurah Mail on Sunday shows a person wearing what appears to be a pointed hood associated with the white supremacist group.
Pinjarra junior football club president Luke Guthrie said he was “truly sorry anyone has had to witness this person and/or this photo”.
“I can assure you all this individual has no involvement at our club and we do NOT condone this sort of behaviour.”
Mr Guthrie said the matter would be “taken further”.
The photo, which did the rounds on social media overnight, was met with disgust by many on Facebook.
One user wrote: “Seriously speechless. I actually do find this offensive and I’m surprised that this person was not asked to leave.”
But another defended the costume and wrote: “They had a dress up for the end of the season, it wasn’t a racist act. So get over it.”
Peel Football League president Geoff Hiller said there would be an investigation into the incident.
Rockingham president Grant Hatch declined to comment.
