A new report alleges sexual misconduct by more than a dozen staff members at a private school in Brooklyn dating back to the 1970s.

The Saint Ann's school in Brooklyn Heights issued a letter Monday, addressing a yearlong investigation into alleged misconduct by male faculty.

According to the school, 19 former staff members were accused of engaging in inappropriate behavior.

The report reveals specific details from six instances, including unwanted kissing and contact at an off-campus party.

The sexual misconduct allegedly took place from the 1970s to the early 2000s, including from the school's founding headmaster, Stanley Bosworth.

"My daughter used to go to Saint Ann's, we had no problems at all. They were very supportive, so I have no idea," a parent said.

"It's incredible, unbelievable, and, you know, people have to be punished. These things shouldn't happen," another parent said. "There needs to be a way for things to be reported."

Saint Ann's said all accused faculty and staff members are no longer employed at the school.
