CLEARWATER — In May, an undercover Clearwater police officer witnessed a woman diagnose a client with lupus using a headset attached to a computer that allegedly scanned the body.

This week, police arrested and charged Veronika Zaitsevskiy, 59, with one felony count of practicing medicine without a license.

Zaitsevskiy operated her business from a second floor office at 1130 Cleveland St., the building that also houses the Tampa Bay Times Clearwater bureau.

According to the warrant, Clearwater Detective Melody Phelps accompanied an undercover informant for a May 11 session of Zaitsevskiy's NLS Diagnostics. The scanner "diagnoses and treats all areas of the body" and can "identify a weak or reduced-function organ" according to the website.

Phelps made an appointment with Zaitsevskiy on Wednesday, and police arrested her at the office.

Zaitsevskiy advertised her business in Comm Line Magazine, a publication affiliated with the Church of Scientology.
