Normal Heights Elementary School was put on lockdown around 4 p.m. Monday, but the lockdown has since been lifted.
Someone reported seeing a naked man at the joint use field next to the school. The field is used by the school and the city.
The school put themselves on lockdown, and police officers responded to the area.
After a short investigation it was determined that the man at the park had pants on, but was without a shirt working out at the field.
School was already out when the lockdown was initiated, but there is an after school program that might have been in session.
