Calaveras High School was put on lockdown Tuesday afternoon due a student who became aggressive with school staff after getting into an argument with girl.

Sgt. Rachelle Whiting of the Calaveras County Sheriff’s Office said the lockdown was a precautionary measure initiated by the school because of concerns that the student may have been possession of a knife when he was “out of control” on campus.

Deputies arrived at about 1 p.m. and no knives or weapons were found and the boy did not face any criminal charges, she said. The boy had calmed down by the time deputies arrived, she said. The parent of the juvenile arrived at the school and he was released to his parent.

A Calaveras County Sheriff’s deputy stayed on the campus until about 2:50 p.m., she said.

It was determined that there was no ongoing threat to students and staff after the child was released to his parents and no weapons were located, she said.

Calaveras High School Principal Mike Tambini did not respond to calls with request for comment.
