ST. CLOUD - St. Cloud Police say Matthew Hull has confessed to making bomb threat calls in the St. Cloud area in order to get revenge against an ex-girlfriend.

Police say Hull tried to disguise his voice as a woman and would leave the name of his ex-girlfriend as the person making the bomb threat. The girlfriend has a restraining order against him.

Hull was arrested Sunday morning in the Princeton area. He's accused of making bomb threat calls to Walmart, St. Cloud Library, Cash Wise East and St. Cloud Hospital.

He is in Stearns County Jail facing four counts of threats of violence, one count of stalking and one count of misdemeanour domestic assault.
