American skateboarder Jason Vanporppal, who recently completed a 5 900km skateboarding journey from Uganda to Cape Town to raise funds for Uganda's first public skatepark, says he has been scammed out of R25 000 intended for the project.

In a video he shared on social media, Vanporppal alleged that a woman who had volunteered to help secure sponsorships for the fundraising campaign kept the money after receiving payment from a brand partnership.

According to Vanporppal, the sponsorship was worth R25 000, which he said was intended to be donated to the GoFundMe campaign supporting the construction of a skatepark for disadvantaged children in Uganda.

Vanporppal said the woman acted as an intermediary between him and the sponsoring company.

"I trusted her with my heart. I trusted her with everything," he said in the video.
