Man on Frontier flight to Denver arrested after 'security threat'

DENVER, June 15 (UPI) -- A Frontier Airlines flight from Tennessee was searched for a bomb after landing in Denver and a passenger was arrested, officials say.

Flight 601 from Knoxville to Denver landed in a remote area of Denver International Airport after a "security threat" was detected, KUSA-TV reported Friday.

FBI agents and Denver police entered the plane and arrested a male passenger, The Denver Post reported.

Passengers left the plane by means of "air stairs," said Laura Coale, an airport spokeswoman. They were taken to a fire station for questioning.

A bomb squad with the Denver police searched the plane and luggage, Coale said. No explosives were discovered.

Flights in and out of the airport were not affected, she said.
