WASHINGTON, US - Police charged a 43-year-old woman with prostitution on Tuesday after she offered sexual services in exchange for tickets to the upcoming World Series.

Susan Finkelstein, of Philadelphia, was arrested after police responded to an advertisement she posted on online classified site Craigslist, the Bensalem, Pennsylvania, police department said on its website.

Finkelstein's ad, which was still posted on Craigslist on Tuesday, described her as a "desperate blond" in need of tickets to the World Series featuring her hometown Philadelphia Phillies against the New York Yankees.

"Diehard Phillies fan - gorgeous tall buxom blonde - in desperate need of two World Series tickets.

Price negotiable - I'm the creative type! Maybe we can help each other! - it said.

Bensalem police said they responded to Finkelstein's ad and filed prostitution charges against her after she "solicited an undercover police officer to perform various sex acts in exchange for World Series tickets."

The Phillies open their defense of their Major League Baseball title against the Yankees in New York on Wednesday.
