MANSFIELD, La. (AP) — Thirty-one people from DeSoto and Sabine parishes have been arrested in a roundup of suspected narcotics dealers.

The Tri-Parish Narcotics Task Force, which is a joint effort of sheriff's offices in DeSoto, Sabine and Red River parishes, identified the alleged street- and mid-level drug dealers through a six-month undercover operation.

DeSoto Parish sheriff's Lt. Ray Sharrow, who heads the task force, said the investigation focused on areas of the community where citizens had been complaining about drug sales taking place on their streets or in neighborhoods.
