ANNAPOLIS, Md. — Two female students from the U.S. Naval Academy have reported being sexually assaulted while on summer training assignments with the Navy away from the school, an academy spokesman said Tuesday.

The Navy Criminal Investigative Service is investigating both cases. No charges have been filed and few details of the alleged attacks were disclosed.

During the summer, academy students, called midshipmen regardless of gender, are assigned to various Navy programs to learn about different aspects of the fleet. Summer training typically lasts about eight weeks and is divided into two, four-week blocks in which midshipmen learn how sailors and junior officers do their jobs.

The academy spokesman, Cmdr. Joe Carpenter, said one case involves a sophomore who made the report in June in Norfolk, Va.

“She returned to the academy,” Carpenter said. “She was assigned a victim advocate and offered counseling.”

Carpenter said the accused is not a midshipman.

In the other case, a junior reported being sexually assaulted in July. Carpenter declined to disclose further details in that case. However, he said the alleged assault didn’t occur in Annapolis, home to the academy.
