An overnight police situation that caused some delays and restrictions overnight at Phoenix Sky Harbor International Airport has been resolved.
Phoenix police investigated something as a precaution, according to airport officials.
The roadway passing Terminal 3 was closed for some time, and access to terminals 2 and 4 was altered. One departing flight was reportedly delayed and airport officials say passengers at Terminal 3 were sent to other terminals.
Operations are reportedly back to normal, but travelers, especially those using Terminal 3 services, should check their airline status before arriving at the airport.
Police have not yet commented on the incident.
