A post on the club's Facebook page said they were not making any public statements while police were investigating.

"It is important that we support those that received injuries at the moment," the post read.

"The police have requested any video footage or photos that anyone has taken."

The Mt Wellington Warriors Rugby League Club refused to comment.
