A gunman is reportedly in a standoff with authorities at Orlando International Airport.

The airport's official Twitter account posted about the incident, saying that police are currently on the scene after an armed man was spotted in the Level 1, A-side of the rental car area.

As you can see in the video above, footage has apparently been leaked of the situation, showing a heavy police presence at the airport.



Another video (below) reportedly shows negotiators speaking with the gunman saying, "You're going to the hospital, not prison."
At this point a portion of the airport has been shutdown, but no delays have been announced. The event has had little impact on operations.

WFTV is reporting that shots have been fired, but no credible news source has confirmed this information.
UPDATE:
According to OPD, a suspect is now "contained" but not in custody, and this is not to be considered an active shooter situation.
UPDATE:
OPD has confirmed that the gunman is now in custody and that everyone is safe. No names or motive have been announced.
UPDATE:

Authorities confirm that the suspect was in mental distress and has been identified as Michael W. Pettigrew, who reportedly told officers to shoot him. Pettigrew has been charged with aggravated assault with a firearm and has been Baker Acted.  According to the arrest report, Pettigrew approached the Mears Transportation desk and told the clerk that he had a gun. He then showed her the handgun multiple times and instructed her to call the police.

It was later determined that the gun was fake.

According to the Orlando Police Department, Pettigrew also told the clerk that he wanted to speak to the president.

After calling 911, Pettigrew was spotted by witnesses with a gun to his head. When approached by police officers, Pettigrew yelled "kill me," but was apprehended about a half hour later (at around 10 p.m.) without incident.
