FBI: Dynamite Found in Baggage

HOUSTON - A suspicious item found in a piece of baggage at Bush Intercontinental Airport on Friday was dynamite, officials told KPRC Local 2. Officials said a suspicious item was found during a secondary luggage check at about 7 a.m., about an hour after the Continental Airlines flight arrived from Buenos Aires, Argentina.

Officials said the item was found during a routine search with a K-9 unit.

Authorities conducted an investigation and found residue from an explosive device on the checked bag.

"Contents of the luggage did contain an explosive component," said Mark Mancuso, deputy director of public safety and technology for the Houston Airport System. "It is a very small amount of explosives, sufficient enough to where it was not necessary to use the threat containment unit that was available. It was carried out by the Houston Police Department and sent for laboratory analysis."

Investigators matched the bag to a 19-year-old college student from Connecticut.

The student was detained at 7 a.m. and questioned, officials said.

Officials said the student told them he was touring mine fields in Buenos Aires and bought the item as an artifact.

Travelers said the student should have known better.
