DFW Airport police finished their investigation into a suspicious truck inside the grounds at Dallas-Fort Worth International Airport Saturday morning.
"The nature of some of the things the officers found on the scene. That prompted them to start an investigation," said DFW Airport spokesman David Magana.
The medium duty truck with a liquid tank mounted on the rear was found abandoned at around 6 a.m. along International Parkway which resulted in the closure of the road leading to Terminal B which is home to American Eagle regional jet service.
Just before 8:30 a.m. airport police finished their investigation and the road to access Terminal B was reopened.
DFW Department of Public Safety officers determined the truck was not a threat and officers contacted the truck's owner.
DFW's spokesman said the truck was supposed to be on the property and belonged to a contractor doing work in the area.
The road closure caused some confusion for American Eagle passengers who were advised to go to Terminal C or D and then take DFW's Skylink people mover to Terminal B.
The road is now open to traffic and no flights have been affected.
