CENTRAL ISLIP, New York - Prosecutors have added a child endangerment charge against a mother accused of posting a suggestive ad on the Web site Craigslist to target a 9-year-old girl.

Margery Tannenbaum, of Long Island east of New York City, is accused of posting an ad that said in part, "I need a little affection." Authorities say she gave respondents the phone number for her daughter's rival, generating at least 22 harassing calls.

Tannenbaum was charged in May with aggravated harassment. She was freed without bail after her arraignment Thursday on that count and the new endangerment accusation.

She pleaded not guilty.

Her attorney, Tad Scharfenberg, declined to comment on the accusations. He said his client is a good person who has no criminal record. Her attorney did not immediately return a telephone call for comment.
