WORTHINGTON, Minn. — One teen is in custody on Thursday, Sept. 19, in connection with a school shooting threat made Wednesday evening on social media, the Worthington Police Department said.

The southwestern Minnesota district began classes two hours late Thursday in response to the threat. "At this time, we believe the threat is not credible," the district reported on its Facebook page.

Due to the suspect’s age, Minnesota law prohibits their identity from being released. In the state of Minnesota, criminal juvenile cases are confidential unless the defendant is 16 or older and charged with a felony.

According to the police, there is no further threat to the public.

District 518 Communications Coordinator Parker Sandhurst said the threat was reported immediately to law enforcement and the district is working closely with the Worthington Police Department.

"Threats to the safety of our students and staff are taken seriously and will always be investigated and pursued," the district released Thursday morning in a statement.

A screenshot of the threat made on Snapchat circulated widely Wednesday night on Facebook. The post included three images of a handgun and the words, "Shooting down the school."
