A Tulsa school was on lockdown Wednesday afternoon.
Officials with Tulsa Public Schools told KTUL that Emerson Elementary was put on a modified lockdown before 11 a.m.
This was after an unidentified man had been yelling outside of the school and then came into the building.
The school is located just north of downtown.
Police were able to locate the suspect and question him. He was released a short time later.
Officials added that the school was under no threat at the time of the incident.
