Police officers had been nearby for an unrelated call so they were able to respond quickly. As they arrived, people from the windows yelled a description of the suspect to police and said he was probably still nearby or in the building.

Bolding was arrested as he left the building. Police said he had a loaded revolver on him at the time and does not have a license to carry.

He is being held without bail. A probable cause hearing was scheduled for June 24.
