LAS CRUCES, N.M.—Federal prosecutors say seven members of a Las Cruces-based prescription drug trafficking ring have been indicted on federal charges.

The U.S. Attorney's Office announced the 14-count indictment Friday. It alleges that the defendants obtained close to 3,200 Oxycodone and Adderall pills over a six-month period and intended to distribute them.

Federal prosecutors say the defendants used fraudulent prescriptions to get the painkillers and stimulants from pharmacies in Las Cruces and Alamogordo.

Three of the people named in the indictment were arrested Friday. They will make their initial court appearance in Las Cruces on Monday.

Two others were arrested in September on a related criminal complaint. The remaining two are in state custody on unrelated charges and will be transferred to federal court to face the charges in the indictment.
