Zachary Shallbetter, 39, of Spokane, Washington, is charged with battery and malicious injury to property, according to Kootenai County booking records. He was booked into the Kootenai County jail but was later released on bond.

The arrest stems from an alleged incident that occurred late Tuesday morning.

According to a Coeur d’Alene police report, Shallbetter entered Banducci’s work office “and threw a large bucket with water and cleaning chemicals on (Banducci).”

A physical altercation ensued, according to the police report. Banducci sustained abrasions on his forearms, and the water and chemicals caused damage to his office, the report said.

After a call to 911, other people helped Banducci subdue the man until police arrived, according to an NIC news release issued late Tuesday afternoon.

Banducci then made a citizen’s arrest, according to the police report.

Shallbetter held a one-year special appointment as an assistant professor, teaching web and graphic design, NIC said in its news release. His contract ended Friday.
