Newly released surveillance footage has captured the tense moment a suspect breached a TSA checkpoint at an Atlanta airport last year, only to be swiftly tackled by a bystander and subdued within seconds. Police released the footage through an open public records request, showing the incident unfolding on the morning of Oct. 30 at Hartsfield-Jackson Atlanta International Airport, Fox 5 Atlanta reported Thursday. In the footage, Leon appears to rush through the airport before attempting to enter the TSA checkpoint. A TSA officer then reacted and reportedly yelled "breach," prompting bystander Mark Thomas to turn around without hesitation. He just kept saying, 'Oh, I'm okay, I'm okay, let me up, let me up, I'm okay'," Thomas said.
