The warning was issued at 3:11 P-M Sunday by the emergency alert system at the University of Wisconsin-Whitewater.  Students were informed there was “an active threat to life safety on campus,” urging them to “RUN, HIDE, FIGHT!”  Four minutes later a large message was posted on the university’s website saying there was no threat to life or safety.  A spokesperson for the school blames a technical issue with the warning system.  University Police Chief Matt Kiederlen apologized to students for any undue stress the erroneous warning may have caused.  He said the mistake is being investigated.
