KANSAS CITY (AP) — Authorities say an armed man was arrested at a Catholic early childhood center in suburban Kansas City after his behavior raised alarms.

The man later identified as Phil Spurgeon entered the school at Our Lady of the Presentation in Lee’s Summit around 11 a.m. Monday.

Police say the receptionist put the facility on lockdown because she noticed the man was “acting erratically.” Staff was able to get the man to exit the building and then locked the door behind him.

Police say an officer found a pistol on him as he was taken into custody.

Spurgeon is in custody in Jackson County awaiting charges.

Our Lady of the Presentation said in a note to parishioners that the “greatest priority is always the safety of the children.” The note added that “children were kept safe and separated from any harm.”
