CONCORD, N.H. (AP) - Federal authorities say several men arrested in Manchester are believed to have ties to a Canadian drug smuggling ring that has funneled drugs and cash through the state.

The Concord Monitor reports the arrests were made Tuesday. The U.S. Attorney's office has scheduled a news conference for Monday afternoon.

Court records say the U.S. Drug Enforcement Administration started investigating the alleged operation in 2008. More than $2 million found inside a pickup truck with New Hampshire plates stopped in Oklahoma was tracked to a drug ring that would traffic marijuana, cocaine, and other drugs into New Hampshire and surrounding states.

Part of the proceeds would be transported to California and used to buy cocaine. The drug would be smuggled back to Canada via New Hampshire.
