Five weight loss clinics of an Indian-origin doctor in Chicago area have been raided by the FBI as part of an "ongoing federal investigation".
Federal agents executed search warrants and searched for evidence yesterday at Gautam Gupta's clinics spread across the city and Rockford, South Beloit, Arlington Heights and Naperville near Chicago.
"The searches were conducted as part of an ongoing federal investigation. No arrests have been made and no charges were filed," an FBI spokesperson told PTI on Saturday.
The spokesperson declined to give further information regarding the investigation or what the agents were looking for.
A woman who answered the phone at Gupta's main office in Rockford declined to comment on the warrants but said the clinic was open and continued to see patients.
According to information on his website, Gupta is a weight loss specialist who uses "innovative FDA-approved medications, along with a weight-loss programme".
It states that Gupta, an MD and board certified in internal medicine, "finds out what works for you and unlocks the mystery to your weight loss frustration".
Advertisements about his "nutrition clinic" offering advice on weight loss have been airing on radio and television across the city.
