KANSAS CITY, Mo. — Three Blue Springs School District campuses were put on a brief lockdown Tuesday after a reported shooting in the area.
Thomas Ultican Elementary School, Blue Springs High School Freshman Center and Blue Springs High School were instructed to shelter in place around lunchtime.
A letter sent to parents said there was an "unconfirmed report of shots fired in the area" and there was a large police presence as a result.
Blue Springs police later said the shooting was unfounded and no one was hurt.
Police handed over the investigation to the district's public safety office.
They determined the gunshot sound to be a noise made by a milk carton popping at the freshman center.
There was an unconfirmed report of possible shots fired near BSHSFC, TUE, and BSHS. The incident was quickly resolved. The report of shots fired was incorrect. The noise heard was due to a milk carton popping at BSHSFC. All three schools have returned to their normal school day.

A police spokesperson further explained that a few students had tried to blow up milk cartons with compressed air.
Classes resumed as normal shortly before noon.
