Port Adelaide are investigating allegations rising star Sam Powell-Pepper assaulted a young woman at an Adelaide nightclub at the weekend.

7 News Adelaide have spoken to a 20-year-old woman who claims the WA product put his hand down her skirt while she was out dancing with friends at Mr Kim’s nightclub in the city centre.

“We're all just dancing on the platform of Mr Kim’s and I feel like a hand go, not just on my butt, like down my skirt, like almost on to my undies,” she said.

“A few moments pass and then the same thing happens. Then I’m dancing with my friend and I feel my arm grabbed so aggressively, that I hit my face on to his chest.

“I look at him and I’m like, ‘what’s your problem’ and then he pushes me. That’s when someone shouts ‘don’t you know who we are’ or something along those lines.”
