A spokesperson for Boston Public Schools told WBZ-TV the device was not on school grounds and students and teachers were not in any danger, but the school was put into safe mode as a precaution.

Police say a neighbor called them to alert them to the device. They’re not sure yet who put it on the sidewalk.

Two pressure cookers were used as explosives in the Boston Marathon bombings last year.

“People are sensitive to this. We’ve had a lot of people go through a serious crisis this year with pressure cookers. It’s no joke. We don’t take it as a joke. We’ll never take it as a joke,” Boston Police Capt. Kelley McCormick told WBZ-TV.
