A pressure cooker spotted outside a school cafeteria caused a scare at a Glen Head high school Wednesday, but it turned out to be a false alarm, Nassau police said.

Police received a call at 10:13 a.m. reporting that a pressure cooker was outside of the school cafeteria at North Shore High School on Glen Cove Avenue, said Nassau Police Det. Vincent Garcia.

The department’s Arson/Bomb Squad responded, but in the interim, “school staff said the science teacher threw out the pressure cooker last night,” Garcia said.

Det. Lt. Richard LeBrun said the school was evacuated as a precaution.

“Nobody was ever placed in any danger,” LeBrun said in an interview on News 12 Long Island.

The school was checked and determined to be safe, News 12 reported.

No one was injured.
