The man had previously been in a standoff with police on the first floor of the airport after he allegedly pointed a gun at an officer in one of the airport's rental auto areas.
UPDATE: OPD has confirmed that the gunman is now in custody and that everyone is safe. Earlier, a crisis negotiator spoke with the suspect before he was taken into custody. Officers then determined it was fake, the police chief said.
Pettigrew is being held for a mental evaluation and faces aggravated assault charges.
It was not immediately clear whether Pettigrew had an attorney.
Airport spokeswoman Carolyn Fennell, according to WKMG, said the standoff occurred in Level 1, Airside A. Police report the call came in at 7:24 p.m.
"I'd rather be a little inconvenienced than have something really bad happen", he said.
It comes after a standoff in the rental vehicle area of the airport, where the suspect communicated with crisis negotiators for two hours Tuesday.
Armed suspect is contained but not in custody. "They knew he was in some type of mental crisis". This is still an active scene with police activity. Several officers can be seen crouching behind walls as a man's voice shouts from outside of frame.
"You're going to a hospital, not prison".
The terrifying situation created confusion and uncertainty at the airport as travelers posted video and photos online of officers with their weapons drawn.
Employees contacted Orlando Police Department and a portion of the airport temporarily placed on lockdown. The incident happened at the rental auto area of Level 1, Side A as per the tweet from the airport.
