A New Town High School teacher accused of destroying one of the school’s printers with a hammer in February has pleaded not guilty.

Thirty-seven-year-old Lukas Kostelecky faces a Class C felony charge of criminal mischief.

Police responded to the school following reports of a "teacher that was freaking out and destroying property."

According to court records, multiple eyewitnesses told police they heard loud noises but did not see Kostelecky destroy the printer.

Kostelecky, who teaches automotive tech at the school, was placed on administrative leave shortly after the incident.

He’ll be back in court June 22.
