NEW LONDON, Conn. — The U.S. Coast Guard says there were five reports of sexual assault or other sexual offenses at its service academy in Connecticut in the 2015-2016 school year.

That’s an increase over the previous year, when there were four reports. There were eight reports in the 2013-2014 school year.

Congress receives an annual report on sexual harassment and violence at the New London-based academy. The academy provided it to The Associated Press on Friday.

Four of the reported offenses were prosecuted. The report says there was insufficient evidence in one case.

In a survey, fewer cadets reported experiencing unwanted sexual contact.

The academy is developing additional training.

Assault reports have risen at the U.S. Naval Academy and U.S. Military Academy, while dropping at the U.S. Air Force Academy.
