Suffolk police arrested a man for making a threat of mass harm at a school in Ronkonkoma.

Police say 63-year-old John Carroll drove into the parking lot of Cherokee Street Elementary School around 3 p.m. Friday and yelled threatening statements at staff members.

Authorities have not yet specified what words he used during the incident.

Police arrested Carrol at his home just after midnight.

Chuck Hollingsworth, who has lived across the street from Carrol for 20 years, tells News 12 he was surprised to hear about the arrest.

“John is a nice guy. He's quiet. He keeps to himself. I really don't understand how this happened to him," he said.

Many who live and work in the area have also expressed anger over the incident.

“To be screaming and yelling at teachers with children around, there's something wrong with you,” said Lake Ronkonkoma resident Joe Dimatteo.

“Who knows what he could've done? I'm glad that they got him,” said Katie Ports of Holtsville.

Carrol’s arraignment, which was originally scheduled for Saturday morning, has been postponed until Sunday.
