Connecticut police are searching for a former CVS pharmacist accused of dispensing private patient information and using it to post a fake sex ad on Craigslist.

A months-long investigation led police in Norwalk, Conn., to file harassment and computer crimes charges against 38-year-old Jonathan Medina, a former pharmacist at one of the chain’s Norwalk stores, FOXNews.com has confirmed.

Police say Medina used a CVS computer to access a patient’s private information, posting her address, phone number and name on Craigslist in an ad for "sex partner wanted" after the customer told him that she would be filing a complaint against him.

Medina no longer works at CVS, and police believe he has fled to Washington state.

Medina’s alleged victim told police that men began calling her and arriving at her home looking for a sex partner shortly after the ad was posted, according to a statement by Norwalk Police Department Lt. Paul Resnick.

One of the callers told the woman that he was responding to a posting on Craigslist, the victim said.

“A thorough investigation was conducted by the Norwalk Police Department’s Patrol Division and Detective Bureau, which developed the necessary probable cause to apply for an arrest warrant,” the statement from the Norwalk Police said.

The charges against Medina come just weeks after the arrest of Philip Markoff, the so-called "Craigslist Killer," who is accused of murdering a New York masseuse he allegedly met through the Web site.

Earlier this month, a woman from Hauppauge, N.Y., was arrested for allegedly using Craigslist to attract men looking for sex, then directing the calls to her neighbor’s home to get revenge for a dispute between the two women's daughters.

On Wednesday, Craigslist announced it will eliminate the "erotic services" section from the Web site in seven days and terminate all ads posted there. The site will replace it with an "adult" category, which the company said it will monitor closely.
