A U.S. Air Force Academy professor has been arrested on the charge of luring a child on the internet, according to police in Colorado.

Capt. Paul Sikkema, who teaches philosophy at the service academy, was recently arrested by investigators from the Arapahoe County Sheriff’s Office on a felony charge.

The charge is a class four felony and generally involves an adult knowingly communicating with a child under 15 years old. During the online communications, the adult usually describes sexual conduct and seeks to meet up in person.

The Arapahoe County Sheriff’s Office did not immediately respond to a request for comment from the Washington Examiner requesting more information about Sikkema’s case.

Sikkema graduated from the Air Force Academy in 2012 before earning his master's degree in philosophy from Georgia State University in 2014. Sikkema started teaching the philosophy department’s ethics course in September 2017, according to his faculty biography.

The Air Force Academy said it plans to comply with the Arapahoe Sheriff’s Department as necessary.

"We are aware of the arrest and can confirm that Capt. Sikkema is a professor here at the academy," Air Force Academy spokesman Ray Bowden told Military.com on Wednesday. "We are tracking his civilian court case as it goes through the legal process, and we will cooperate fully as needed with the Arapahoe Sheriff's Department."
