Rhode Island ? A medical student jailed in Boston on suspicion of killing a masseuse he met on Craigslist was charged Monday in an arrest warrant with pulling a gun on a stripper in a Rhode Island hotel.

The warrant accuses Philip Markoff of assault and weapons violations. Authorities had previously said Markoff was the suspect in the April 16 robbery attempt at a Holiday Inn Express in Warwick.

A Las Vegas stripper told Rhode Island authorities that she was bound with cord and held at gunpoint by a man she met through the Craigslist classified advertising Web site. She said her assailant fled when her husband came up to the hotel room.

Markoff, a second-year medical student at Boston University, was charged with the April 14 killing of Julissa Brisman, a 25-year-old New York City resident who advertised on Craigslist, at the Boston Marriott Copley Place hotel.
