UPDATE: According to the state's attorney, the case against Joshua Delvecchio was dismissed.

A 19-year-old Fairfield University student has been charged with sexually assaulting a female student on campus last fall.

Joshua Delvecchio of Madison was charged Thursday, following an investigation spanning more than two months, with first-degree sexual assault, first-degree unlawful restraint and third-degree assault.

The incident took place in October, according to the report, when the female student told police that she had been sexually assaulted by a male she did not know. She had to be treated at an area hospital for injuries, police said.

In addition to witness accounts of the attack, police said evidence linking Delvecchio to the incident was gathered from electronic communications between him and other students. Other evidence was provided by public safety officers and administrators at the university, police said.

Forensic evidence, according to police, was used to refute Delvecchio's account of the incident.

In the aftermath of the assault, students on campus were advised that a sexual assault on campus had occurred and were told to take precautions, in accordance with university policies.

In a statement issued Thursday by Fairfield University, school officials said they are cooperating "fully" with police.

"The university is committed to providing a secure living and learning environment free of all forms of sexual violence and harassment," said the statment from Michael Horyczun, the university's director of media relations. "This matter has already been referred to the Dean of Students Office for processing through the university's disciplinary system. That process is separate from actions occurring in the court system."

Delvecchio was told to leave campus pending the investigation, police said.

He surrendered at police headquarters Thursday after learning a warrant for his arrest had been issued. Bond was set at $50,000, and he is scheduled to appear on the charges Jan. 10 in Bridgeport Superior Court.
