Federal authorities say three baggage handlers at Oakland International Airport are among 14 people charged as part of a marijuana smuggling ring.

U.S. Attorney Melinda Haag said Monday that the baggage handlers are accused of using their security badges to get through screening areas while carrying suitcases filled with marijuana. They would hand off the luggage to passengers waiting to board planes, who would transport them as carry-on to cities nationwide.

According to the complaint, the group was operating as early as July 2012.

The baggage handlers were identified as Kenneth Wayne Fleming of San Leandro, Keith Ramon Mayfield and Michael Herb Videau of Oakland.

Haag says the three men have been charged with conspiracy to distribute and possession with intent to distribute 100 kilograms or more of marijuana.
