In a statement, a spokesperson for Phoenix Sky Harbor International Airport confirmed the incident to PEOPLE, adding that while the incident briefly halted some operations in Terminal 4, it has since been “resolved” and most operations are back to normal.

The spokesman declined to comment on the airport’s gun policies, instead referring inquiries on the subject to Phoenix police.
