Horace Mann bans registered sex offender dad

Scandal-plagued Bronx private school Horace Mann — still smarting from allegations that it harbored sexual molesters on its staff for years — has barred from campus a third-grader’s father who was arrested for attempted sexual abuse in 2001.

The tony institution embarrassed the young child of Eric Wahl, 55, a millionaire marketing executive, by blasting an e-mail to the lower grades of the K-12 school.

“I write to share that Horace Mann School has recently learned that a father of a second-grade student is listed on the publicly available Connecticut Sex Offender Register as the result of a 2002 conviction,” school head Thomas Kelly wrote to parents in a May 2013 letter than included a link to Wahl’s registration.

“As soon as the school learned of the listing of this parent on the CSOR, we met with the family and barred the father from coming to the school or to any school function at any time in the future.”

“The school continues to welcome the child and mother as members of the school community.”

Some parents were shocked and upset because many of them let their daughters sleep at Wahl’s home.

The Post reported on Wahl’s arrest in 2001, when he was caught inappropriately chatting online with a person who he believed was a 13-year-old girl but was actually an undercover cop.

The Riverdale school, which is still dealing with the aftermath of its own sex scandal, looked into the matter after a parent complained.

According to a source close to Wahl’s estranged wife, one of the parents at the school noticed Wahl looking at their daughter at a birthday party.

His wife filed for divorce last October.

A school rep defended the e-mail blast.

“As soon as the School was made aware of Mr. Wahl’s presence on the Connecticut Sex Offender registry, we acted responsibly and in a timely way to inform our community and ensure the safety of our students,” the rep said.

In 2012, it was revealed that more than 50 students had been sexually abused by teachers from the 1970s through the 1990s.

“I’m glad to see HM erring on the side of protecting children from sexual predators,” molestation survivor Joseph Cummings, class of 1977, wrote in an e-mail to The Post.

“Of course they have not always done that in the past but I’m happy to see them doing it now in the present.”
