Law enforcement said there is currently no threat to public safety.

Passengers deplaned and were rescreened during a 4-hour pit stop in Tucson, before they finally made their destination.

One passenger managed to take cell phone video of the whole thing and posted it to Twitter.

Two F-16 fighter jets escorted the plane to TIA.

Officers then took the passenger into custody and handed him over to the FBI for investigation.

No one was hurt in this situation, and everyone returned to the plane once it was cleared for take-off around 8 p.m.

At one point another passenger spoke up for the man – saying he was his guardian and the passenger takes medication.

The FBI hasn't identified that passenger yet.

Tucson News Now is working to learn more details about this investigation and what caused the man to make threats.
