A K-9 unit was brought in to help search for the suspects in a west side Madison armed robbery overnight. Police say...two men armed with a handgun and "bear mace" walked into the Topper's pizza in the 78-hundred block of Mineral Point Road shortly after 11-30 and demanded all the money from the establishment.

After getting the cash, they robbed the employees and a customer of their wallets and ordered them into a storage freezer.  Officers say...this incident does not appear to be related to a string of similar crimes around the city.

No one was hurt.
