BASIN, Wyo. (AP) — A health care provider in northern Wyoming is being investigated by the Wyoming Division of Criminal Investigation and the Drug Enforcement Administration.

South Big Horn Hospital District Board of Trustees Chairman Todd Denny revealed the investigation last week but declined to provide details, including what was being investigated.

The hospital board began cooperating with investigators in February.

News of the investigation comes as the South Big Horn Hospital District undergoes administrative changes, which have attracted some public criticism.

The district includes a hospital in Basin.
