VIDALIA — A Clayton man was arrested by the U.S. Drug Enforcement Administration Monday on charges he was involved with what was allegedly one of the biggest Oxycontin distributing outlets in the United States.

The Louisiana State Police reportedly arrested Ples Edward Dobbins, 40, 153 Dianne St., Clayton, as he was driving north of the Peck area on Louisiana 15.

At the same time, the Concordia Parish Sheriff’s Office seized a number of vehicles at his residence, including a 2006 F350 Ford dually pickup truck, a 2004 BMW 745 LI automobile, a 2003 Suzuki racing motorcycle, a 2006 Dodge Magnum automobile, a 14-foot wide utility trailer and four ATVs, according to a statement from the CPSO.

“I’m extremely glad that the CPSO could assist federal agents in this case,” Sheriff Randy Maxwell said in a statement. “All items were seized without incident, and the level of cooperation in this case among law enforcement officials around the state was fantastic.”

A conspiracy indictment has been handed down on Dobbins earlier this year for his alleged connection with the Reddi Care Ambulatory Clinic, in Baton Rouge, the Maximum Urgent Care clinic, in Lafayette, and Stanton Trinity Urgent Care, in New Orleans, which allegedly distributed more Oxycontin than any other outlet in the United States, the statement said.

The clinics were shut down by law enforcement agencies in January.

The arrest, which was accompanied with other arrests around the state, came after a three-year investigation into alleged drug trafficking.

Allegations in the indictment include that the ill-gained funds were laundered and then used to make purchases of automobiles and real property.

Other agencies involved in the investigation included the U.S. Attorney’s Office, the IRS, the Louisiana State Police, the Kenner Police Department and other local agencies.

CPSO narcotics officers Billy Joe Ratcliff and Larry Lawrence collaborated with the DEA agents Monday morning.

Indicted in the case with Dobbins were Deshawn Whatley, 29, of Baton Rouge, Jimmy Lee Winters, 28, and Joshua Williams, 23.

Other indictments connected with the case included Lafayette physician Joseph Braud, 81, Hahnville pharmacist Thadrian Johnson, 47, and Candice Wilson, 35, and Monica Jones, 38, both of Baton Rouge.
