A New Jersey high school student accused of lacing his Spanish teacher's iced coffee with saline solution has been charged with aggravated assault.

Authorities tell the Asbury Park Press (http://on.app.com/1OExPm1) that it happened Tuesday morning at Central Regional High School in Berkeley Township. They say the student was released to his parents' custody, pending a juvenile court hearing.

School officials say the teacher had gone into a hallway, leaving her coffee at her desk, when the student poured a few drops of saline solution into the cup. The teacher drank the coffee and started feeling stomach discomfort. She was treated at a hospital.

Ingesting saline solution can lead to nausea, vomiting, restricted breathing and a coma.
