A Marshalltown High School student was tased Monday after police say he was a threat to himself and others.
Marshalltown Police Chief Mike Tupper says the 15-year-old student was disruptive and refused to leave class or cooperate with the school resource officer, Kraig Lageschulte.
Authorities say the juvenile then resisted arrest and fought with the SRO and a juvenile court officer.
Officer Lageschulte used a Taser to restrain the 195 pound teen as he became violent, police say.
The juvenile was uninjured and is now a juvenile detention facility charged with disorderly conduct, interference with official acts and misdemeanor assault.
The incident is under review but Chief Tupper says the use of force was reasonable and within department policy to stop the teen from hurting himself and others.
