Security issue closes 2 checkpoints at Sky Harbor Airport terminal

PHOENIX - Phoenix police say two of the four security checkpoints at Terminal 4 of Sky Harbor International Airport are temporarily closed while authorities check out what a Police Department spokesman calls "an unfamiliar unusual found item."

Police Sgt. Vince Lewis and airport spokeswoman Heather Lissner says passengers still can use the terminal's B and C checkpoints while the A and D checkpoints are temporarily closed Monday morning.

Also, Lissner says vehicle traffic temporarily cannot use Terminal 4's southside curb area.

By 7:45 a.m., the all-clear was given and checkpoints A and D re-opened.

Terminal 4 is the airport's busiest terminal, housing hub operations of American and Southwest airlines.
