He was left with some minor injuries including head pain, and lost his glasses, a hat and an e-cig during the incident. But he's aware it could have been much worse.

Blythe says: "I've hurt myself worse skateboarding, so it's nothing I can't shake off. It was regrettable, but to a great degree it was also my own fault for not paying more attention to my surroundings. I knew better, but I got distracted taking photos.
