MENOMONEE FALLS, Wis. (CBS 58) -- A FedEx employee reportedly fired dozens of gunshots inside a distribution center in Menomonee Falls. 

Police were called to the distribution center located on County Line Road around 9:40 p.m. on Sunday, March 16 to investigate a report of a subject who entered the building with a semi-automatic handgun. 

Shortly after officers' arrival, a single gunshot was heard from inside. As officers approached the building, a 27-year-old Milwaukee man -- identified as a current FedEx employee -- exited a side door with a handgun in his hand. 

Officials say the suspect initially obeyed officers' orders to drop his weapon but then resisted. The man was subdued by officers, arrested, medically cleared at a local hospital and then transported to the Waukesha County Jail. 

It was determined the suspect discharged 25 rounds inside the facility. 

Other than a minor abrasion suffered by the suspect during his arrest, no other injuries were reported. 

The suspect, identified as Isaiah Dorsey, is charged with:

• Armed burglary
• Criminal damage to property, use of a dangerous weapon
• Resisting an officer

In court Tuesday, Dorsey's cash bond was set at $100,000. 

A hearing is set for March 26.
