STATEN ISLAND, N.Y. — A public school in Castleton Corners initiated shelter-in protocols on Tuesday afternoon.

A text alert issued around 2:15 p.m. by the New York City Department of Education notified parents and guardians of students at PS 29 at 1581 Victory Blvd. of the situation.

“P.S. 029 Bardwell is Shelter-in. Everyone is safe. BRT (building response team) is activated. Do not come to P.S. 029 Bardwell. No one is permitted to enter or leave the building until it is lifted…”

A source with knowledge of the incident said that an individual had managed to climb up scaffolding and make their way onto the roof of the school building.

A photo provided to the Advance/SILive.com from the scene shows several individuals who appeared to be wearing police uniforms on the scaffolding.

By 3:50 p.m., there was no sign of the emergency response or an individual on the roof.

Following dismissal, parents still gathered in the vicinity of the school told an Advance/SILive.com reporter they had received notification of an individual who had climbed onto the roof.

The parents went on to say that they weren’t particularly concerned about the situation.

This is a breaking news story. Additional information will be posted as it becomes available.
