Florida ? Two airline baggage handlers used their employee uniforms and identification cards to enter restricted areas, bypass screeners and carry a duffel bag loaded with guns and drugs into a plane’s passenger cabin, according to court documents released Wednesday.

A tip led authorities to investigate the men aboard the Delta flight headed for Puerto Rico on Monday afternoon, said Carlos Baixauli, a Miami-based special agent with the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives.

Christopher White, a spokes-man for the Transportation Security Administration in Washington, said passengers were not in danger. He declined to address the security breach on the plane.

Thomas Anthony Munoz, 22, was arrested when he got off the plane at the Luis Munoz Marin International Airport in San Juan. Authorities found 13 handguns, one assault rifle and eight clear bags containing a total of 8 pounds of marijuana in the duffel bag he was carrying, Baixauli said.

Zabdiel J. Santiago Balaguer was arrested late Tuesday. The men, both of Kissimmee, were charged with conspiracy to distribute marijuana and possessing firearms in interstate commerce during a drug trafficking offense, court documents said.
