Federal investigators on Monday were still sorting through information gathered during a raid of the offices of a Billings rheumatology doctor.
Don White, a spokesman for the Health and Human Services branch of the Office of Inspector General in Washington, D.C., would only confirm that a raid had taken place on Friday of the offices of Dr. Enrico Arguelles in Billings.
Because it's an open investigation, White declined to comment on the nature of the raid or discuss for what specifically officers were searching.
Arguelles practiced in the Arthritis & Osteoporosis Center PC, in Billings. He's one of three providers at the practice, which was open on Monday.
