LORAIN, Ohio -- Police in Lorain are launching an investigation involving a sex act that allegedly took place at a local elementary school.

NewsChannel5 reported that the students believed to be involved in the alleged incident are third-graders at Frank Jacinto Elementary School.

Police said they are investigating a sexual act one third-grade boy performed on another boy in a school hallway.

Detective Mark Carpentiere said they get reports all the time of children engaged in such acts, and he said such incidents are always cause for concern because it could be a red flag for abuse.

The child told authorities that he learned the behavior from his father's pornography. His parents denied this and no charges will be filed, although family services has been notified.

Police said the incident was consensual, but experts said parents in this and similar cases should be aware of signs that their child is suffering from a traumatic event.

Signs such as trouble sleeping, nightmares, bed-wetting and change in appetite could be signs that a child is in need of help.

Lorain schools Superintendent Dean Schnurr said disciplinary action is being considered against both students, and letters are being sent home to inform students about the incident.
