A former student has sued Daniel Webster College, saying the New Hampshire institution was negligent in failing to protect him from a fellow student who harassed and assaulted him, The Telegraph, a newspaper in Nashua, N.H., reported today.

The plaintiff, Jerid Vilardo, enrolled at Daniel Webster in 2004, and within two weeks another student was antagonizing him, according to the lawsuit. One time the bully, who is not named in the lawsuit, opened Mr. Vilardo’s windows and struck him repeatedly with a lacrosse stick while he lay in bed, the suit says.

Mr. Vilardo argues that his dormitory was improperly supervised and its staff members insufficiently trained. He says administrators should have known that the bully had a history of hazing and abuse, and they should have expelled him once they learned of his behavior, which Mr. Vilardo brought to their attention. The college eventually expelled the bully, the lawsuit says, but he apparently continued to appear on the campus and harass Mr. Vilardo, who finally dropped out.

The lawsuit says Mr. Vilardo “had a reasonable expectation that he could rely upon the college’s obligation as both an educational institution and a residential program to maintain a safe environment.” Mr. Vilardo is seeking an unspecified amount in damages. —Sara Lipka
