The father of a student at the Shahar middle school in Hod Hasharon on Friday struck his child’s teacher for confiscating the student’s cellphone.

The parent entered the classroom around 10 a.m. and, before the entire classroom, hit the teacher.

The Shahar middle school has a policy which forbids students from using their cellular phones in school. If a student violates the rule, a teacher is permitted to confiscate the device and return it later to the student or parent at the end of the day.

Kfar Saba police arrived shortly thereafter and arrested the man and took him in for questioning. The police advised the school to hold an anti-violence educational activity with police officers.

Because of the incident, the teachers’ union decided to go on strike on Sunday for two hours in protest.
