KANSAS CITY, Mo. — A student at a Kansas City charter school was released from police custody to parents after the student allegedly made threats on social media.

The threat caused Citizens of the World Charter Schools to cancel class Tuesday. The school is located at West 35th Street and Broadway Boulevard. The school learned about the threat on social media late Monday evening.

Kansas City police officers recommended the student face municipal charges and forwarded the case to city prosecutors.

The school notified families on Facebook and by email Tuesday morning. School leaders also told families they would provide more information as it becomes available. The school also posted the message on its website.

Some parents asked the school why they weren’t notified Monday night. The school responded that based on timing, the school waited until it believed most caregivers were up to see the message. School leaders said they feared emails and texts would get lost if the school sent the information in the middle of the night.

The school did not provide specific information about the threat. The police department said investigators believed there was not an active threat to anyone at the school. There are no additional safety concerns as of Tuesday afternoon, according to investigators.

KCPD officers who are assigned to that area of the city plan to keep watch for any issues at the school.
