Authorities say a man unhappy with the service at Alltel threatened to blow up the cell phone company’s Madison Avenue store.

Matthew Shannon Brady, 35, of Glencoe, was taken into custody Sunday by McLeod County sheriff’s deputies and transported to the Blue Earth County Jail.

Mankato police say he may be charged with terroristic threats and disorderly conduct for calling the company’s Madison Avenue store and saying, “I’ll be there on Tuesday but you better have a S.W.A.T. team at Alltel because I’m going to blow up the building and everyone inside.”

Authorities say Brady called the Alltel store on Madison Avenue and, after hearing a recording of the store’s hours that day, went to the store when he thought it would be open.

When he got there and found the store closed, he called Alltel to complain.
