Prosecutors: Charges upgraded in airline gun smuggling case

Prosecutors have upgraded charges in a gun trafficking case in which they allege at least two Delta Air Lines employees helped take guns on commercial flights in carry-on luggage from Georgia to New York.

Brooklyn District Attorney Kenneth Thompson says five people have been charged. Three face charges of aggravated enterprise corruption, which carries a penalty of up to life in prison upon conviction. They had faced enterprise corruption charges before.

Four of the people were arrested in December 2014. The fifth worked as a Delta ramp agent and was arrested last week in Georgia.

Prosecutors say weapons including an AK-47 were carried aboard commercial jets. More than 150 guns were seized during the seven-month gun trafficking probe.

Atlanta-based Delta Air Lines Inc. has said it cooperated with the investigation.
