An assistant principal at Sand Creek High School who was arrested Thursday for investigation of misdemeanor theft has resigned, school officials reported today.

Rob Schlup, 34, is accused of taking $400 from the athletic department.

He allegedly admitted he took the money, which was found in his home, Colorado Springs police said.

Schlup was placed on paid leave Monday, but resigned today, said Doug Peden, human resources executive director for Falcon School District 49.

The school has recovered the money, he said.
