Her jail-house Houdini act was short-lived.

A 23-year-old woman busted for making harassing phone calls was slapped with a new felony, after she pulled a disappearing act and vanished from an NYPD precinct in Brooklyn last night.

Amanda Jackson, 23, was arrested about four hours after she slinked away from the station on East New York Ave., at around 10 p.m. Police didn’t say how she managed her getaway, but sources said she was not handcuffed at the time.

Jackson now faces an additional charge of felony escape.
