A Delaware man found outside a Westfield elementary school with a loaded gun and additional ammunition is now facing numerous charges.

Union County prosecutors say police went to the Tamaques School in Westfield just before 4 p.m. Thursday after authorities in Delaware told them a man later identified as Thomas Wilkie was headed there and might be armed. Officers believed that Wilkie may have been “in crisis” according to police radio transmissions.

Classes had already concluded for the day, but the school went on lockdown because after-school activities were still taking place.

Authorities say Wilkie had a 45-caliber handgun loaded with hollow-point bullets and two more loaded clips of ammunition on him when he was arrested. They say another 130 additional rounds were found in the trunk of his SUV.

The 46-year-old Bear man faces weapons and trespassing charges. It's not known if he's retained an attorney.

Authorities haven't said why Wilkie drove to the school or why he was armed.
