SIOUX FALLS, S.D. (AP) — State authorities have launched an investigation into drugs at South Dakota's mental health hospital in Yankton.

Attorney General Marty Jackley declined to tell the Argus Leader newspaper what his office is looking for, citing the ongoing investigation. But he referred to the probe as "a controlled substance investigation."

The Yankton County Sheriff's Office was called two weeks ago to investigate an incident in which methamphetamine was brought into the Human Services Center. Sheriff Jim Vlahakis said the incident involved a patient.

National Alliance on Mental Illness official Phyllis Arends says the incident might call for the hospital to take a closer look at security.

The hospital provides chemical dependency treatment for adults. It's run by the state Department of Social Services, which has declined to comment on the investigation.
