Aurora Univ. offers $25,000 reward after threat

The university canceled classes and employees were sent home on Wednesday. A police sweep of the campus found nothing suspicious. University President Rebecca Sherrick said in a statement that the school intends "to seek full redress for the costs and inconvenience incurred."

The university said it received three or four emails containing non-specific bomb threats. The president called the emailed threats "an act of domestic terrorism." The reward money is for information leading to the identification and apprehension of the person responsible.

Aurora University is about 40 miles west of downtown Chicago.
