LOS ANGELES, Calif. (KTLA) -- The son of a former Los Angeles fire chief is among 5 people who plead guilty to charges of bribing a Transportation Security Administration agent at LAX to allegedly help him smuggle marijuana aboard a flight.

Millage J. Peaks IV, 24, son of former L.A. Fire Chief Millage Peaks, was arrested in 2011 on suspicion of bribing a public official.

Two former TSA agents -- Dianna Perez, 28, of Inglewood, and Randy Littlefield, 29, of Paramount -- also pleaded guilty to allegedly accepting the bribe, FBI officials said Tuesday.

Charles "Smoke" Hicks, 24, of Culver City and Andrew "Drew" Russel Welter, 25, of Fontana were also charged with conspiracy.

Peaks was attempting to carry marijuana onto a flight to Boston, officials said. They claim he offered Perez between $5,000 and $6,000 to help him bring the drugs onto the plane. Perez told agents Peaks paid her about $3,000 for her trouble, according to a criminal complaint.

Officials say Peaks tried to smuggle 10 to 15 pounds of marijuana in 14 plastic bags hidden in his luggage.

Peaks told FBI agents that Perez helped him smuggled marijuana onto flights leaving LAX on nine other occasions, according to the criminal complaint filed against him. He also said Perez told him that she helped someone else smuggle marijuana onto flights but "business" has recently stopped.

Authorities made both arrests after a baggage handler smelled the drugs in a bag and alerted his supervisors, officials said.

Both TSA agents were terminated last October.

Peaks' father, the former fire chief, retired from his post earlier this year. His sister is an officer with the LAX Police Department. Both said they had no knowledge of the alleged drug smuggling.

All 5 defendants are expected to appear in federal court on August 14.
