A Cook County prosecutor has been charged with misdemeanor battery and criminal trespass for allegedly becoming disruptive at a Chicago adult store.

Sarah Naughton, a four-year assistant state's attorney, is accused of biting a store worker in the leg Saturday when she was asked to leave.

Authorities say Naughton and a companion, both appearing to be intoxicated, were asked to leave shortly after they entered the store. However, Naughton became belligerent and bit a worker. According to authorities, her companion, Bradley Gould, shoved the worker and made "menacing gestures" to him.

The store owner took the clerk to a nearby hospital for treatment.

State's attorney spokesman Andy Conklin says the 31-year-old Naughton has been placed on administrative leave.

It's was not immediately known if Naughton and Gould obtained legal representation.
