ATLANTA, Ga. -

Authorities say they're trying to recover more than 100 rifles stolen from a boxcar that was parked in an Atlanta train yard.

U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives spokesman Richard Coes told The Associated Press that the weapons were taken from a CSX rail yard along Marietta Boulevard, on the city's northwest side.

Coes said they include "AK-style" rifles. He declined to discuss other aspects of the case.

Gary Sease, a spokesman for Jacksonville-based CSX Corp., said the company is cooperating with law enforcement to recover the weapons.

CSX said in a statement the company is working with law enforcement officers in "a rigorous investigation led by them."

Authorities said the rifles were stolen on or around Nov. 12.
