A threat was made against Sioux Falls Roosevelt High School on the online discussion forum Reddit Tuesday morning, police say.

"We have had a lot of tips come in, which is something we really like to see," SFPD Public Information Officer Sam Clemens said.

Extra officers will be on hand at Roosevelt Tuesday morning due to the threat. However, authorities say the school day will continue like normal.

According to Clemens, police are working with the FBI to investigate the person responsible for making the post.

The threat was made on a Sioux Falls discussion board within the website Reddit shortly before 5:00 a.m.
