Multiple reports are emerging out of Comic-Con International this afternoon of a scuffle over seats in Hall H, ending in a stabbing. The massive room, where many of the film presentations are held, was locked down, and a man led away in handcuffs by police.

Although details are scarce at the moment, Dread Central reports the fight erupted just as the Resident Evil: Afterlife panel was ending about 4:45 p.m. PST. The fight between two attendees allegedly broke out when one of them refused to change seats. According to Dread Central, one man stabbed the other in the eye with a pen.

The lockdown of Hall H means panels for Paul and Cowboys & Aliens have been delayed, leading the hotly anticipated Marvel Studios presentation to be pushed back.

Comic Book Resources is attempting to contact Elite Security, the San Diego Police Department and area hospitals for more details. We'll update as more information is available.

Update: CBR has details from San Diego police, and photos of the suspect.
