Police are looking for thieves who stole a cache of rifles from an Atlanta rail yard.

Railroad shipping company CSX officials said 120 rifles of different calibers were stolen two weeks ago from a shipping container.

CSX has its own police agency that patrols the railroad’s 21,000-mile network, and those officers are leading the investigation with aid from other agencies.

Spokesman Gary Sease would not specify what type of weapons – whether they were assault rifles or hunting rifles – were taken.
