KUSA - All schools in a suburb of Colorado Springs will be closed on Wednesday after police say they found a credible threat in a girls' restroom at a high school.

All activities and athletics in the Woodland Park School District are also canceled for Wednesday.

The threat -- that was specifically for Wednesday -- was found on Feb. 23 in a Woodland Park School District bathroom. Woodland Park Police have been investigating since then.

Police deemed the threat credible, but did not elaborate on what exactly the threat was.

Woodland Park School District encompasses the northern half of Teller County.

The investigation is reportedly ongoing.

Police are offering a $500 reward for information leading to the identity of the person responsible for the threat.

On Feb. 21, a student was taken into custody after making a "vague" and "general" threat of violence against Bear Creek High School. That 17-year-old student has since been charged with "interference with staff, students at an educational institution," according to Lakewood Police.

Just a few days before that, The Cherry Creek School District and the Aurora Police Department investigated a similar online threat made against Grandview High School in Aurora.

Threats were also made against Dakota Ridge and Columbine high schools on Feb. 19.

Investigators later determined that a 16-year-old had made the threats as a "joke" and will likely face criminal charges.
