SAN FERNANDO VALLEY (AP) — Federal authorities have arrested nine men in the San Fernando Valley as part of a yearlong investigation into a firearms trafficking ring.

The Bureau of Alcohol, Tobacco, Firearms and Explosives said Wednesday that the arrests came after an undercover probe in which an ATF agent infiltrated the group and exposed the selling of stolen firearms, machine guns and silencers.

According to a federal indictment, some of the weapons had been stolen from homes.

In all, 58 firearms were seized during the probe.

One of the defendants was arrested on state charges unrelated to the case and three suspects remained at large.
