ELYRIA — A 16-year-old Elyria boy was charged with carrying a concealed weapon and domestic violence yesterday after he was caught with a knife at Elyria High School.

According to a police report, the teen was taken out of class by a security officer because he was playing with a lighter. While in the office, a principal asked him to empty his pockets, and he produced the knife, a silver locking knife with a 4-inch blade.

The principal also discovered a plastic baggy that had apparently contained marijuana, but officers were unable to charge him because there was no residue remaining in the bag, the report said.

The officer was called back to the office after the student punched his father in the face, causing his nose to bleed, the report said.

The principal said that the teen was not listening to his father and was attempting to leave the office, and the two began to wrestle, which led to the punch. The teen’s father was seen by the school nurse, the report said.

The father said that he did not want to boy to return home, so he was transported to the detention home.
