(CNN) Lauren McCluskey was both concerned and frustrated when she called Salt Lake City Police on October 19.

A convicted sex offender whom she had met just a month earlier was continually harassing her after she ended their short relationship. But police at the University of Utah, where she was a student, weren't doing enough to put a stop to it, she said in a call to 911.

"I'm worried because I've been working with the campus police at the U, and last Saturday I reported and I haven't gotten an update," she told Salt Lake City Police dispatch.
