A 13-year-old student of a Honolulu private school was arrested Tuesday morning after he allegedly threatened his teacher who had confiscated items from the child.

The 30-year-old teacher told the student that his items would be returned, but the student was angry and threatened the teacher, according to a police report.

The school in downtown Honolulu was not identified by the police nor were the items that were confiscated. The student faces a possible terroristic threatening charge, police said.
