DENVER - Authorities are investigating after a passenger allegedly made a comment on Saturday that he had an explosive device on an aircraft at Denver International Airport.
According to officials as DIA, the passenger was accused of making the comment as the airplane pulled away from the jetway, but before it was able to take off.
DIA Spokesman Chuck Cannon says the man said he had the explosive C-4 on Northwest flight 552, bound for Minneapolis.
"Northwest flight 552 going from Denver to Minneapolis has been delayed due to a security issue," said Northwest Airlines Spokeswoman Michelle Aguayo Shannon. "One passenger was taken by authorities from the aircraft. Northwest apologizes to our customers for the delay and for the inconvenience."
The plane was towed away from the airport terminal while the threat is being investigated, officials say.
Denver Police confirmed one person was taken into custody and no explosives were found, however, they continued to search the plane.
