A York County grand jury has indicted a former Massachusetts state trooper on charges of rape and aggravated assault in Kittery on a woman he met through a social networking site.

Police say Joseph Silva, 54, of Newburyport, Mass. arranged to have dinner with the woman on Nov. 22 in Portsmouth, N.H. and then invited her to his room at the Roadway Inn in Kittery, ostensibly to watch a New England Patriots football game.

Silva is charged with raping the woman and assaulting her. Police say she was treated at a hospital.

Silva was arrested in December.
