MYRTLE BEACH – Police have arrested 15 people as they conducted raids in nearly a dozen locations along the Grand Strand in a bid to break up a marijuana operation run by Hell’s Angels.

Interim Horry County Police Chief Saundra Rhodes said Monday that the 18-month investigation focused on breaking up the cultivation, distribution and trafficking of marijuana involving the Hell’s Angels chapter.

Police are still looking for 19 other suspects. Officials say all of them either are a member of the biker organization or are affiliated with them.

The amount of marijuana seized was not released. Police would not say how much they think was distributed by the local organization.

Most of the suspects arrested Monday are from Myrtle Beach.
