INSIDE EDITION is learning more about the shocking moment when a panicked driver plowed through a crowd during the annual zombie walk.
The zombie-walk is a highlight of Comic-Con in San Diego, attracting thousands who dress up as zombies and walk through the streets for fun.
But this year's zombie walk took a genuinely scary turn as a driver in a black Honda honked his horn after being surrounded by zombies.
Cops said a handful of zombies began pounding on the hood of the car. That was when the driver panicked, hit the gas and sped away.
Paige Tallent, who was dressed as a zombie and witnessed the chaos told INSIDE EDITION, "People pop up on the hood, I'm sure in an effort to say 'hey knock it off', and then he just screeched out."
A 64-year-old woman, who was just watching the zombie walk and wasn't a participant, suffered a serious arm injury.
Bystanders rushed to help her, including Tallent, who's a nurse.
"All of us took our shirts off, including myself, and we just all wrapped them around her arm enough to stop the bleeding," explained Tallent.
Spectators chased the car until it stopped a few blocks away.
The driver's panic may be understandable. A video of the driver shows he is deaf and used sign language to communicate with a police officer.
Cops said his two small children, who are also deaf, were in the backseat and became frightened by the zombies surrounding the car, which had its wind sheild shattered.
It sounds like something right out of the Brad Pitt movie, World War Z.
The driver who plowed into the crowd at the zombie walk wasn't arrested.
But that wasn't the only Comic-Con controversy. As usual, the event was packed with women in sexy comic character costumes, but some of the women reported they were groped and sexually harassed.
Adrianne Curry, the first winner of America's Top Model, dressed up as Silk Specter from the Watchmen comic, and said groping is a big problem at Comic-Con.
"Women are going to stop coming here dressed as our favorite characters if people keep acting like fools," said Curry.
