THE BRONX - Horace Mann School in the Bronx has issued a formal apology for sexual abuse allegedly perpetrated by teachers and staff over the past 50 years.

In a letter posted on the school's website, the school's board says, "We sincerely apologize for the harm that was caused by the teachers and administrators who abused anyone during their years at Horace Mann School. These unconscionable betrayals of trust never should have happened. But they did." Administrators say they also plan to create an advisory board of student safety.

Last month, dozens of former students came forward with their stories of abuse going back to the 1960s, with some saying they were raped when they were as young as 11 years old. The Bronx district attorney said the school staff wasn't able to be prosecuted over the allegations because the statute of limitations had expired.
