Reports are emerging of a stabbing that occurred in Hall H at San Diego's Comic-Con this afternoon before the "Paul" and "Cowboy and Aliens" panel. The stabbing allegedly occurred over an argument between two men about seating. After the jump, we have a Tweet Reel video that supposedly shows the alleged attacker being arrested.

As reported at USA Today, San Diego Police Sgt. Gary Mondesir said, "Two males got into a dispute and one male stabbed the other male with a pen around the eye socket. Parademics arrived almost immediately and took the victim to the University of California/San Diego hospital. The suspect was taken away.

"We had officers inside the convention center and they were there relatively quickly, and citizens had actually detained the suspect," said Mondesir.
