The incident, caught on video, happened right outside a security checkpoint
Three people were stabbed at Hartsfield–Jackson Atlanta International Airport on Wednesday.
The Atlanta Police Department (APD) said in a statement that officers confronted a woman brandishing a knife just outside a security checkpoint.
"Officers engaged the female, attempting to talk her into dropping the knife and working to restrict her movement and move travelers from the area," authorities said. "During the encounter the female suspect stabbed an adult female and then an APD lieutenant as he attempted to take her into custody."

APD said they tackled the woman and only after taking her into custody did they learn of another stabbing victim before their confrontation.
"The preliminary investigation indicates the female was inside a taxi and stabbed the driver, prior to arriving at the airport," police continued. "Upon arriving at the airport, the female exited the taxi and walked into the airport where officers encountered her a short time later."
