An OB-GYN who lost his medical license two years ago was arrested Wednesday after police say he illegally performed surgical procedures at a cosmetic surgery center on Cobb Parkway, according to a release from Cobb County police.

Cobb County police obtained warrants for Nathaniel Johnson III, 55, on July 8 as officials investigated whether he performed surgery without a license at the Hello Beautiful Cosmetic Surgery Center and the Royal Advanced Health Care at Vinings.

“We had a female come to us and indicate she had a couple of procedures done,” Cobb police spokeswoman Alicia Chilton told Channel 2 in a July 8th interview. Johnson restarted a business in Cobb, but it closed about late June, the news station reported.

Johnson's license was revoked in 2014 after he admitted to Medicaid fraud and employing an unlicensed doctor, The Atlanta Journal-Constitution previously reported. His medical license wasn't reinstated.

Johnson owned Regency Professional Health Services for Women, where he billed Medicaid more than $217,000 in expenses. He was given a 10-year sentence, but only served six months in the Fulton County Jail.

“There are definitely concerns there are more victims out there who underwent procedures,” Chilton told Channel 2. “He may have written prescriptions for them and was doing all that without a license.”

Johnson is being held in the Cobb County Detention Center. Detectives are asking anyone who may have been in contact with Johnson since July 18 to call them at 770-499-3945.
