A third woman has reportedly accused leading Republican presidential candidate Herman Cain of inappropriate behavior in the workplace.

She alleges she received unwanted comments from Cain during his tenure as head of a restaurant lobby group. The woman said he made sexually suggestive remarks or gestures about the same time that two co-workers had settled separate harassment complaints against Cain, who was then the head of the National Restaurant Association.

She did not file a formal complaint because she began having fewer interactions with Cain, she said.

The woman spoke only on condition of anonymity, saying she feared losing her current job and the possibility of damage to her reputation. She was located and approached by the Associated Press as part of its investigation into harassment complaints against Cain.

Meanwhile Cain's presidential campaign is accusing rival Rick Perry's operation of being behind the stories about sexual harassment allegations against Cain in the 1990s.

Perry's people denied any involvement in the story and suggested the campaign of yet another candidate, Mitt Romney, might be a source.
