Authorities in northern New Jersey say a doctor who admitted to sex crimes involving female patients has been practicing recently under a different name.

Alan Lupinacci was arrested Tuesday.

The Bergen County Prosecutor's Office says that beginning in January 2010, Lupinacci had been practicing under the name Alan Woods at The Institute for Natural Health and Wellness in Wyckoff.

He also has hosted a live call-in radio show on New York's WMCA.

In 1995, Lupinacci lost his medical license after pleading guilty to 10 counts of criminal sexual contact with female patients.

The 65-year-old now faces theft, impersonation and misconduct charges as well as a charge of unlawfully practicing medicine.
