2 p.m. update: District 518 issued a press release noting that an arrest was made in connection to the threat made Wednesday night to ISD 518 .

The release noted that school functions will continue as normal with raised security remaining in place.

"If your student is not in class today, please contact your student’s building," the release stated. "ISD 518 is always working to ensure the safety of all of our students. Part of this process is being able to account for every student, present and absent, who are normally in our facilities. This is standard procedure for ISD 518 for every school day.

"Due to the increased amount of absences, it has been difficult to account for all students. It is important to let your student’s building know if they will not be attending classes. "

District 518 also offered its thanks to local authorities for their "assistance and hard work."

"It was with their guidance and support that the school district was able to make informed, safe decisions for our staff, students and community," the district's press release stated. "It is due to the dedication the officers from the Worthington Police Department exhibited that the situation was resolved in a timely and safe manner. ISD 518 encourages our staff, students and community members to thank the Worthington Police Department for their rapid response and hard work concerning this situation."

12:50 p.m. update: One is in custody in connection with a school shooting threat made Wednesday evening on social media, the Worthington Police Department announced in a press release.

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 WPD, there is no further threat to the public.

Original report: WORTHINGTON — Independent School District 518 will begin two hours late today with increased security after receiving a possible threat Wednesday night.

The threat is not believed to be credible, the district reported to its Facebook page.

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".

Sandhurst said the remainder of the day will follow the normal two-hour late schedule.

According to Sandhurst, the district’s decisions reflect the meetings and discussions that occurred between the district and Worthington Police Department Wednesday night and early Thursday morning.

The district credited the community for quickly reporting the threat. The district asked that staff, students and the public continue to be vigilant and report any suspicious activity to local authorities.
