A Southern California man has been arrested again for allegedly practicing medicine and treating patients despite holding no medical license to do so.
Nitun “Nate” Dayalghai Ahir, 44, now of Thousand Oaks, was arraigned Monday in Ventura County for practicing medicine without a license. Ahir was out on bail at the time following a previous arrest for the same alleged crime last month.
According to the Ventura County District Attorney’s Office, Ahir “represented himself as a doctor at Regen Spine & Nerve in Ventura.” Despite his previous charges, Ahir returned to the business and began treating patients again just days after his arrest, according to complaints submitted to the D.A.’s Office.

As per the terms of his previous release, Ahir was explicitly told not to provide any medical services to any patients, offer any services or take any payments, or else he’d be taken back into custody.
He now faces a new crop of charges for practicing medicine without a license, as well as a charge for using the term “Doctor” and the “Dr.” prefix to imply he is a licensed medical professional.
According to the California Department of Consumer Affairs, Ahir holds no medical license in California, including as a doctor, surgeon, nurse, nurse practitioner, chiropractor or otherwise. He is also not a licensed physician in any other state, officials said.
Between the two arrests, Ahir faces charges for practicing medicine without a license, as well as charges of identity theft and theft from an elderly or dependent adult.
The charges include special circumstances that accuse him of targeting particularly vulnerable victims in a well-planned and sophisticated scheme that involved him violating a position of trust.
After posting $50,000 bail, Ahir is out of custody again and is due back in court on June 25, the D.A.’s Office said.
