Cameron Aulner doesn't think of himself as a hero. The wheelchair-bound Colorado resident says he just did what anyone else would do when he stopped a child molester from fleeing the scene at the Walmart where he works.

Witnesses say a man sexually assaulted a young girl inside a Walmart in Westminster on Sept. 19, and then tried to flee the store, KDVR FOX 31 TV reported.

Aulner, 22, was working at the Comcast table in the front when he heard a bystander yelling to stop the man from leaving the store. He tackled the suspect, 34-year-old Kevin Salyers, before he could escape and held him until cops arrived, he said Tuesday in an interview with KDVR.

“It was something that happened so fast, I didn’t even think about it,” Aulner told the station. “I’m not a hero, I just did what you’re supposed to do.”

Salyers was arrested and charged with sexual assault on a child, police told FOXNews.com on Wednesday.

Aulner has been in a wheelchair since he fell from a roof while hanging up Christmas lights, he told the station. He said he might get an award from police for his actions.
