Police say attempted drug transaction, shooting preceded Phoenix airport terminal's lockdown

Police in Arizona say an attempted drug transaction was behind a shooting that led to a three-hour lockdown of the busiest terminal at Phoenix Sky Harbor International Airport.

Tempe police say the attempted drug transaction and shooting took place at a Tempe gas station Thursday afternoon. Three suspects were pursued to the airport in nearby Phoenix where two were quickly apprehended.

A third suspect remained at large as hundreds of officers searched Terminal 4. He ultimately was found hiding in a parking garage. The lockdown resulted in 25 flight cancellations.

Lt. Mike Pooley says the three suspects were arrested and booked into jail on suspicion of multiple crimes.

According to Pooley, the person who was shot during the alleged attempted drug transaction is hospitalized and expected to live.
