A 13-year-old boy was charged Friday after allegedly bringing a knife to North Harford High School where he is a student.
Two students told school administration that they saw a third student, who is in eigth grade, with a knife in school, said Edward Hopkins, spokesman for the Harford County Sheriff's Office.
The student allegedly was found with a sheathed, six-inch survival style knife, Hopkins said.
Hopkins explained no one at the school was harmed and the student made no threat to himself or others.
The 13-year-old was charged as a juvenile with possession of a knife on school property and released to the custody of his father.
There had been no other arrests or weapon incidents in Harford County Public Schools as of 3 p.m. Friday, Hopkins said.
Schools were on alert Thursday and Friday based on circulating and unfounded rumors of violence in connection with the Mayan myth of the world ending Dec. 21. Harford County sheriff's deputies made extra patrols of county schools as a precaution Friday.
