Kamehameha Schools has acknowledged cases of unauthorized dorm room entries at its Kapalama campus and said it has dealt with those cases appropriately.

Michael Chun, headmaster of Kamehameha Schools' Kapalama campus, mentioned the unauthorized dorm entries during a meeting with members of the Kamehameha 'ohana on Moloka'i this month.

In a telephone interview Tuesday, Chun said the incidents aren't pervasive. He noted that students are sometimes found at the wrong place after hours, such as the schools' athletic facilities, at the schools' swimming pools or in other students' dorm rooms.

A 12-year-old girl was allegedly sexually assaulted in her Kapalama campus dorm room by two 13-year-old boys over a three-day period last month.

But Chun said the case involving the boarding student is the only instance he's aware of that resulted in allegations of serious harm.

School officials have since enhanced campus security — both physically and procedurally — and are considering additional measures, said school spokesman Kekoa Paulsen.

Students caught in areas where they are not supposed to be are disciplined in accordance with the school's code of conduct, he said.

Pohai Ryan, a 1980 Kamehameha Schools graduate, said the case has raised concerns among alumni and parents about the adequacy of staffing and monitoring on campus.

"No matter how you look at it, what happened is not good," she said.

The parents of the 12-year-old girl have expressed anger at school officials for not calling police after hearing of the allegations and have not ruled out a civil lawsuit against the school.

Eric Seitz, an attorney for the family, declined comment Wednesday when asked about security on the campus.

"We're not doing anything else at this point other than to attend to the kid's immediate needs," Seitz said.

The girl has been placed on leave at the family's request.

She reported to campus officials on Aug. 31 that she was assaulted by two schoolmates on that day and on two previous days. School officials did not notify police, despite a state law requiring them to do so. Her parents made the call to police after arriving at the Kapalama campus.

Two Kamehameha Schools Middle School students were arrested on suspicion of six counts of first-degree sexual assault and five counts of third-degree sexual assault.

School officials initially defended not calling police.

"When alleged student misconduct is reported at Kamehameha Schools, our first priority is to ensure the safety and emotional security of the student," Ann Botticelli, vice president for community relations and communications for the school, stated earlier this month. "We also begin an immediate investigation of the allegation, and as soon as we have reason to believe a serious incident occurred, we notify the students' parents, and we assist and support the parents if they decide to report the incident to the police."

But amid criticism from some legal experts and education officials, the school now says it will file police reports in all incidents involving violence and harm to students.

Founded by the will of Princess Bernice Pauahi Bishop, the Kamehameha Schools is a nonprofit trust that educates children of Hawaiian ancestry.

With assets of more than $7.7 billion, the trust is one of the nation's wealthiest charitable estates and is the state's largest private land- owner.

There are about 3,200 students on the Kapalama campus. Of those, 550 are boarders, according to the school's Web site.
