Federal authorities have raided a South Carolina cigarette distributor as part of a two-year, multistate investigation into illegal cigarette sales.

The FBI says a search warrant was executed Thursday at Holley Sales Group in Anderson.

The bureau says the raid is tied to similar searches over the past two months at cigarette manufacturers in Russell Springs, Ky., and Cynthiana, Ky., and a distributor in Tupelo, Miss.

Those searches followed the April discovery of a warehouse in Mississippi containing millions of dollars worth of contraband cigarettes.

No arrests have been made. An FBI spokeswoman wouldn’t give any more details about the ongoing investigation.

Messages left with Holley’s owner and vice president were not immediately returned.
