Pima County Sheriff's officials announced Monday that 51-year-old Gustavo Nunez has been booked into jail on suspicion of two counts of practicing medicine without a license.
Sheriff's deputies investigated a report of suspicious activity Saturday evening at a home near the Omni Tucson National Golf Resort.
They say Nunez was performing the fat-removal procedure on multiple victims at his house.
It's unclear if Nunez has a lawyer yet.
The Arizona Daily Star reports that Nunez was previously arrested last August on felony charges, including possession of dangerous drugs and practicing medicine without a license.
A three-month investigation by federal authorities reportedly uncovered evidence that Nunez performed illegal medical procedures at his clinic known as NuTec.
