A Marshalltown Police Department vehicle sits outside of the high school on Friday as students leave the building following a lockdown. No one was hurt.

The Marshalltown High School went into lockdown this afternoon at 2:30 p.m. The lockdown ended at around 3 p.m.

Marshalltown Police Department Chief of Police Mike Tupper said a person connected to a concerning social media post was located at a traffic stop made by MPD detectives. That person is at the MPD station with investigators, he said.

“The person has not been arrested and no charges have been filed at this time,” Tupper said.

No weapons of any kind have been recovered.

The police department did not ask the school to go into lockdown, but the district made the decision to do so out of an abundance of caution.

Tupper said the investigation is ongoing.

“We are trying to piece everything together,” he said. “Right now it is just attributed to the one person. The language used was concerning and we [the police department and the school district] are taking steps to make sure everyone at the school is safe. These calls are high priority for us and we devote a lot of resources to them.”

Marshalltown School District Communications Director Adam Sodders said the school district is working closely with the police department and have determined there is no credible threat. Sodders said all students and staff are safe. The high school returned to a regular school day with a 3:25 p.m. release.
