The students and teachers at PS 234 were evacuated this morning after a caller threatened to come to the school with a bomb. A call came to 911 at 8:53 from the school; it was evacuated minutes later, police said. The kids were on the streets nearby for a bit, then taken to another location. They returned to the school around noon.

The Emergency Services Unit and the K9 unit both responded to the call, along with several of FDNY squads and trucks. There were no injuries and no arrests. The investigation is ongoing, police said.

The NYPD has said that these calls are not uncommon and they rarely amount to anything, but obviously everyone involved has to take it seriously.

Last month, a couple of local private preschools received a call from unknown person who threatened to “shoot up the school.” Also in those cases, there are no arrests and the investigation is ongoing.
